Re: [xsl] Failing string() test fail

[Karl Stubsjoen <kstubs@xxxxxxxxx>]

OK, this is XSLT 1.0 (I should get in the habit of mentioning that)
The general idea is to display a group heading with child heading and
child detail below each child heading, with the following rules in
place:
1)  only display a group heading if 1 or more child details items occur
2)  only display a child heading if 1 or more child details occur
I'd say the above is typical, well, common anyhow.
I have proven that my context is valid with xsl:comment(s) like <!--
YES I AM HERE -->
I have dummed down the xml (see below) and written similar xpath
expressions, as a sanity check.  So now I am wondering what is it I
could be doing wrong.  I can't freely post the xml and xsl source, as
this is a solution for a client.
I will continue to test and experiment but am afraid that I might have
to resort to a workaround.  The demands on this report are pretty
steep leading up to this point with left to right pivoted groupings
requiring a few recursive template calls, and following::sibling types
of selects.
Is it possible that I have overworked the engine, found a bug?  It
would be my 2nd in about 5 years if I had!
