XLink Namespace Declaration

Sets up the namespace prefix and URI to use in the XLink linking attributes


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.
