This is a convenience function for treating an XSL document
as an XML document so that we can process its contents directly,
e.g. finding templates and parameters, using XPath expressions.
(This is different from parsing the XSL document for use within
XSL transformations. In that case, we use
xsltParseStyleSheet
).
This function optionally allows the caller to have xsl:import and xsl:include nodes be substituted by reading the referenced XSL files and having their contents inserted in place of the xsl:import/xsl:include nodes. This "flattens" the XSL document and makes querying its contents easier.

the base URL relative to which references to other XSL
files in xsl:import and xsl:include nodes are resolved.
Typically one does not need to specify this at the top-level

Currently, we replace the xsl:import and xsl:include nodes with the corresponding xsl:stylesheet node. In the future, we may replace the import/include nodes with the children of the stylesheet nodes.

object that represents the parsed XML document.
