Extension instructions (XSLT only)

A Saxon extension instruction is invoked using a name such as <saxon:localname>.

The saxon prefix (or whatever prefix you choose to use) must be associated with the Saxon namespace URI http://saxon.sf.net/. The prefix must also be designated as an extension element prefix by including it in the extension-element-prefixes attribute on the xsl:stylesheet element, or the xsl:extension-element-prefixes attribute on any enclosing literal result element or extension element.

However, top-level elements such as saxon:collation and saxon:script can be used without designating the prefix as an extension element prefix.

The extension instructions and declarations are:

• saxon:assign

• saxon:call-template

• saxon:collation

• saxon:doctype

• saxon:entity-ref

• saxon:import-query

• saxon:while
