Global parameters are defined on the stylesheet level.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:para name="param1" select="'default-string'"/> </xsl:stylesheet>
Global parameters can have a default value, specified by the select statement.
Global Parameters can be used to pass values from external applications to the stylesheet.
