<xsl:param> - XSLT: Extensible Stylesheet Language Transformations 编辑

The <xsl:param> element establishes a parameter by name and, optionally, a default value for that parameter. When used as a top-level element, the parameter is global . When used inside an <xsl:template> element, the parameter is local to that template. In this case it must be the first child element of the template.

Syntax
