Three xsl changes:

1. If there are no directives for a module, print "This module provides
no directives."

2. Add the type="section" parameter for <directive> and
<directivesynopsis>.  The < and > should not be included.  They will
be added by the transformation.

3. All fragment anchors (internal page links) go to lowercase.
