public final class GlobalParam extends GlobalVariable
The compiled form of a global xsl:param element in the stylesheet or an external variable declared in the prolog of a Query.
The xsl:param element in XSLT has mandatory attribute name and optional attribute select. It can also be specified as required="yes" or required="no". In standard XQuery external variables are always required, and no default value can be specified; but Saxon provides an extension pragma that allows a query to specify a default.
