        through the native or the TrAX API</LI>
      <LI>get an <CODE><FONT face="courier, monospaced">InputSource</FONT></CODE> for the document to include, either
        from the <CODE><FONT face="courier, monospaced">SourceLoader</FONT></CODE> or from the document's URI</LI>
      <LI>parse the input document using the compiler's XSLT parser</LI>
      <LI>set the import precedence of the included stylesheet to the same as
        the import precedence of the including stylesheet</LI>
      <LI>get the top-level stylesheet from the XSLT parser</LI>
      <LI>move all variables, parameters, and top-level elements (include
        templates) from the included stylesheet to the top-level stylesheet

    <P>This is very similar to <CODE><FONT face="courier, monospaced">&lt;xsl:include&gt;</FONT></CODE>, but import
    precedence has to be handled differently. Looking at the code you'll find
    this fragment:</P><DIV align="right"><TABLE border="0" cellpadding="0" cellspacing="4" width="464"><TR><TD bgcolor="#0086b2" height="1" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD><TD bgcolor="#0086b2" height="1" width="462"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="462"></TD><TD bgcolor="#0086b2" height="1" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD></TR><TR><TD bgcolor="#0086b2" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD><TD bgcolor="#ffffff" width="462"><FONT size="-1"><PRE>
    // Handle precedence for the including stylesheet
    final int currPrecedence = parser.getCurrentImportPrecedence();
    final int nextPrecedence = parser.getNextImportPrecedence();
    _imported.setImportPrecedence(currPrecedence);
    context.setImportPrecedence(nextPrecedence);</PRE></FONT></TD><TD bgcolor="#0086b2" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD></TR><TR><TD bgcolor="#0086b2" height="1" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD><TD bgcolor="#0086b2" height="1" width="462"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="462"></TD><TD bgcolor="#0086b2" height="1" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD></TR></TABLE></DIV>

    <P>The important thing here is that the imported stylesheet has import
    precedence <B>less</B> than the importing stylesheet. So the imported
    stylesheet gets the current import precedence, while the current stylesheet
    gets the next available (unused) import precedence. The
    <CODE><FONT face="courier, monospaced">Stylesheet</FONT></CODE> class has a method
    <CODE><FONT face="courier, monospaced">setImportPrecedence()</FONT></CODE> that ensures that the import precedence
    is set not only for the stylesheet itself, but that it is also propagated
    down to any included/imported stylesheets:</P><DIV align="right"><TABLE border="0" cellpadding="0" cellspacing="4" width="464"><TR><TD bgcolor="#0086b2" height="1" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD><TD bgcolor="#0086b2" height="1" width="462"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="462"></TD><TD bgcolor="#0086b2" height="1" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD></TR><TR><TD bgcolor="#0086b2" width="1"><IMG alt="" border="0" height="1" hspace="0" src="resources/void.gif" vspace="0" width="1"></TD><TD bgcolor="#ffffff" width="462"><FONT size="-1"><PRE>
