Attribute: extension-element-prefixes
(of element
<stylesheet>)
Standard excerpt:
A namespace is designated as an extension namespace by using an extension-element-prefixes attribute on an xsl:stylesheet
element or an xsl:extension-element-prefixes attribute on a literal result element or extension element. The value of both
these attributes is a whitespace-separated list of namespace prefixes. The namespace bound to each of the prefixes is designated
as an extension namespace. It is an error if there is no namespace bound to the prefix on the element bearing the extension-element-prefixes
or xsl:extension-element-prefixes attribute. The default namespace (as declared by xmlns) may be designated as an extension
namespace by including #default in the list of namespace prefixes. The designation of a namespace as an extension namespace
is effective within the subtree of the stylesheet rooted at the element bearing the extension-element-prefixes or xsl:extension-element-prefixes
attribute; a subtree rooted at an xsl:stylesheet element does not include any stylesheets imported or included by children
of that xsl:stylesheet element.
