General
Introduction
2.1 Introduction
The XWiki Syntax 2.0 has proven to be quite useful and robust in general; however since its introduction a few shortcomings have been found. The corresponding improvements have been consolidated in XWiki Syntax 2.1. Some new features of this syntax are:
•	Homogenize the link and image syntax for better clarity, consistency and extensibility.
•	Added ability to display icons, to embed images via the Data URI scheme, to link to files using the UNC notation and to link to relative URLs.
Since XWiki Syntax 2.1 is based on XWiki Syntax 2.0 all syntax from XWiki Syntax 2.0 is valid unless the 2.1 specifications suggest differently.
General Remarks

XWiki Syntax 2.1 Link Specification
Legend: The parts in () are required, while the parts in [] are optional.
The full format of a link is [label>>] (resource) [||parameters]
•	label: An optional string which will be displayed to the user as the link name when rendered. The label may contain XWiki Syntax. If no label is specified a default label will be generated. The generation pattern can be changed, see the Admin Guide. Example: My Page
•	resource: A required string with the link reference in one of the following forms
•	URL: Any URL in the form of [url:](protocol://path). Examples: http://xwiki.org, url:https://svn.xwiki.org/
•	url: An optional string identifying the resource as an URL.
•	protocol://path: The URL itself
•	Wiki page: A reference in the form page:[(wikiName):](pageNameList). Examples: page:Page, page:myxwiki:Page, page:ParentPage.ChildPage.SubChildPage, page:../SiblingPage, page:./ChildPage
•	page: A required string identifying the resource as an XWiki page. The same reference can be used for either a terminal or non-terminal page, if both exist it will lead to the non-terminal page.
•	wikiName: An optional string containing the name of a wiki. The link will point to a page inside that  wiki. If no wiki is specified, the current wiki is used. Example: mywiki
•	pageNameList: A required list of slash-separated wiki Pages names pointing to the final linked wiki Page syntax. It's also possible to use . and .. to indicate current or parent page/wiki. Examples: Main, A/B, A/B/C, ../Sibling, ./Child
•	Wiki document: A reference in the form [doc:][[(wikiName):](spaceNameList).](documentName). Examples: doc:Welcome, doc:Main.Welcome, doc:mywiki:Main.Welcome, Welcome
•	doc: An optional string identifying the resource as an XWiki terminal page. A non-terminal page can also be referenced this way, but it must append its .WebHome part (e.g. doc:Sandbox.WebHome).
•	wikiName: An optional string containing the name of a wiki. The link will point to a page inside that wiki. If no wiki is specified, the current wiki is used. Example: mywiki.
•	spaceNameList: An optional dot-separated list of wiki Space names. If no space is specified the current space is used. Examples: Main, A.B, A.B.C
•	documentName: A required string containing the name of the linked wiki page. Example: Welcome
•	Wiki space: A reference in the form space:[(wikiName):](spaceNameList). Examples: space:Main, space:mywiki:Main, space:A.B.C
•	space: A required string identifying the resource as an XWiki non-terminal page (i.e. a space).
•	wikiName: An optional string containing the name of a wiki. The link will point to a page inside that wiki. If no wiki is specified, the current wiki is used. Example: mywiki
•	spaceNameList: A required list of dot-separated wiki Space names pointing to the final linked wiki Space (or non-terminal page). Examples: Main, A.B, A.B.C
•	InterWiki page: A reference in the form interwiki:[(interWikiAlias):](pageName). Example: interwiki:wikipedia:XWiki
•	interwiki: A required string identifying the resource as an InterWiki link.
•	interWikiAlias: An optional Inter Wiki alias as defined in the InterWiki Map (see the Admin Guide). Example: wikipedia
•	pageName: A required string containing the name of the linked page. Example: XWiki
•	Attachment: A reference in the form attach:{{{(wikiName):}(spaceNameList).}(pageName)@}(imageName)
•	attach: A required string identifying the reference as an XWiki Document attachment.
•	wikiName: An optional string containing the name of a wiki. The image reference will point to an image attached to a page inside that wiki. If no wiki is specified, the current wiki is used. Example: mywiki.
•	spaceNameList: An optional dot-separated list of wiki Space names. If no space is specified the current space is used. Examples: Main, A.B, A.B.C
•	pageName: An optional string containing the name of the wiki page to which the referenced image is attached. Example: Welcome
•	attachmentName: Name of the attachment as it is stored in the wiki. Example: photo.png
•	Page Attachment: A reference in the form pageAttach:{{{(wikiName):}(pageNameList)/}(imageName)
•	pageAttach: An required string identifying the reference as an XWiki Page attachment.
•	wikiName: An optional string containing the name of a wiki. The image reference will point to an image attached to a page inside that wiki. If no wiki is specified, the current wiki is used. Example: mywiki.
•	pageNameList: An optional dot-separated list of wiki page names. If no page is specified the current page is used. Examples: Main, A/B, A/B/C
•	attachmentName: Name of the attachment as it is stored in the wiki. Example: photo.png
•	Email address: A reference in the form mailto:(emailAddress) (#anchor is not valid). Example: mailto:john@smith.com
•	mailto: A required string identifying the resource as email.
•	emailAddress: Targeted email address. Example: john@smith.com
•	Relative path: A reference on the server in the form path:(relPath). Example: path:$doc.getURL('reset') produces target address http://server.domain.com/xwiki/bin/reset/Space/Page where /xwiki/bin/reset/Space/Page is produced by $doc.getURL('reset').
•	path: A required string identifying the resource as a relative path.
•	relPath: A required string containing the relative path of the resource on the server that shall be linked.
•	UNC (Windows Explorer): A reference in the form unc:(path). The link is rendered as a file:// link. Examples: unc:C:\Windows\, unc:\\myserver\path\img.png, unc:home/user/somefile
•	unc: A required string identifying the resource as a UNC (Windows Explorer) path.
•	path: A required string containing the local path of resource accessible by the user. Examples: C:\Windows\, \\myserver\path\img.png, home/user/somefile
•	Untyped: If none of the above-mentioned resource types are specified (i.e. no type: resource prefix was specified in the link), then the link will be treated as a link to an XWiki terminal or non-terminal page using the following algorithm:
•	Terminal page in the current space, only if it exists. Example: [[A]] is resolved to the equivalent of [[doc:currentSpace.A]]
•	Non-terminal page  in the current space. Example: [[A]] is resolved to the equivalent of [[space:currentSpace.A]], which is the equivalent of [[doc:currentSpace.A.WebHome]]
•	If the current page is non-terminal and the previous 2 checks above did not find an existing page, 2 additional checks are made:
•	Terminal page as sibling in the parent space, only if it exists. Example: The [[B]] link inside the non-terminal page A.C is resolved to the equivalent of [[doc:A.B]]
•	Non-terminal page as sibling in the parent space, regardless if it exists or not. Example: The [[B]] link inside the non-terminal page A.C is resolved to the equivalent of [[space:A.B]], which is the equivalent of [[doc:A.B.WebHome]]
•	Note1 - Absolute links: If the untyped link has 2 or more dot-separated components specified (i.e. that look like a space name and a page name), the above algorithm will resolve the page relative to the current wiki, and not the current space. Example: [[A.B]] can be resolved to either [[doc:currentWiki:A.B]] (if it exists) or to [[space:currentWiki:A.B]] (equivalent of [[doc:currentWiki:A.B.WebHome]]) and not to [[doc:currentWiki:currentSpace.A.B]] or [[doc:currentWiki:currentSpace.A.B.WebHome]].
•	Note2 - Special handling of .WebHome: If the untyped link ends in .WebHome, it will always be handled as a terminal page. Example: [[A.WebHome]] will always be resolved to the equivalent of [[doc:A.WebHome]] and not to [[doc:A.WebHome.WebHome]].
•	parameters: An optional list of space-separated parameters passed to the link. Example: queryString="mydata1=5&mydata2=Hello" anchor="HTableOfContents" target="_blank"
•	queryString: An optional query string for specifying parameters that will be appended to the link target address and used in the rendered URL. Example: url:http://domain.com/path||queryString="mydata1=5&mydata2=Hello" produces target address http://domain.com/path?mydata1=5&mydata2=Hello
•	anchor: An optional anchor name pointing to an anchor defined in the referenced link. Note that in XWiki anchors are automatically created for headings and images. Example: url:http://domain.com/path||anchor="HTableOfContents" produces target address http://domain.com/path#HTableOfContents
•	target: An optional parameter that allows to open link target in new window. Example: target="_blank"

•	parameters: An optional list of space-separated parameters passed to the image. Example: width="800" height="600" alt="img.png" title="My nice image"
•	HTML attributes: All attributes defined by the HTML standard will be added to the rendered HTML <img> tag.
•	style: CSS style information that should be applied to the image. Examples: style="float:right;height:50" (image on right side, height 50 px), style="display:block;margin-left:auto;margin-right:auto;width:80%" (image centered, width 80% of block width), style="vertical-align:bottom" (text starts at bottom of picture)
•	height: A parameter that defines the height of the displayed image. The value should be presented either in pixel (example: height="80") or in pixel related to the height of the block containing the image (example: height="40%").

•	title: A parameter that defines the title the displayed image which will be visible when hovering the mouse trigger over the image, for instance. Example: title="My nice image"
•	alt: A parameter that defines which text should be displayed if the browser is not able to display the image. Since this is a required HTML attribute XWiki will use the file name instead if the alt parameter is not defined. Example: alt="img.png"
•	More: A more in depth explanation on the HTML <img> tag including more attributes can be reviewed in the HTML standard.
•	queryString: Allows queries to be passed to the server when creating the download link for the referenced image. Example: queryString="width=100&height=800&keepAspectRatio=true" (keepAspectRatio=true will fail if the width and height parameters are specified in addition to queryString!)

Parameters
2.0 Parameters
With XWiki Syntax 2.1 it's possible to pass parameters to the different syntax elements and also to blocks of text. This is used for example to style them. You can set any parameter key/value pair you want. The XHTML renderer will pass these parameters as XHTML attributes to the underlying XHTML representation of the different syntax elements.
