Defines the name of the parameter.


(Optional) XPath expression defining the default value for the parameter, which is used if the person or client application that executes the script does not explicitly provide a value. The select attribute or the content of the <xsl:param> element can define the default value. Do not specify both a select attribute and content; we recommend using the select attribute so as not to create a result tree fragment.
