/*
	This template file is unusual. Instead of echoing HTML to send to a user's
	browser, these functions return components for XSLT stylesheets that will be
	used to transform XML data.

	The format for function names is different from typical SMF template files.
	This is intentional. The format has two variants:

	1. xslt_generic_{descriptive name}

		For XSLT elements that can be used in any XSLT stylesheet. They must be
		completely agnostic about the data they handle.

	2. xslt_{source type}_{result type}_{descriptive name}

		For XSLT templates that transform a specific type of XML source document
		into a specific type of result document. For example, XSLT templates
		that transfrorm the XML of a SMF profile export document into HTML use
		'xslt_export_html_' as their function name prefix.
