%XLINK.xmlns.attrib;
XLink Namespace Declaration
Sets up the namespace prefix and URI to use in the XLink linking attributes. See W3C XLink documentation or use the W3C documentation for the XHTML1.1 table model. (http://www.w3.org/TR/xhtml-modularization/abstract_modules.html#s_tablemodule).
Remarks
The attribute-like “xmlns:xlink” is not a true attribute,
but a namespace pseudo-attribute. All namespace prefixes must be associated with a URL, and
the prefix “xlink” has been set to the URL for the World Wide
Web Consortium (W3C) XLink Recommendation.
