xlink:href

Href (Linking Mechanism)

Provides an address or identifier that permits an XLink application to find a remote resource, for example, a URI (such as a URL or filename), to link to an online site associated with the author or the online definition of a term.

Remarks

Of the many linking attributes that may be used, @xlink:href is the most important, since it provides the link. The attribute is required for those elements which must link, and it is optional on other elements only in the sense that an element need not link. If an element links, this attribute is required.
