I just realized that ignoring the fragment identifier is actually
safer (or at least easier).

Consider:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xml:id="me"
 >
   <xsl:import href="#me" />

</xsl:stylesheet>

Saxon reports error XTSE0210 whereas Gestalt goes into an infinite
loop.

So in order to be conformant, Gestalt has somehow to check that the
fragment identifier does not refer to a module already in action.

I shall have to consider how to do this.
