Im not sure if I completely understand what you are trying to do. Ive checked
your mentioned thread it seems that you are really trying to use template
matching rules to group/ungroup, include/exclude data elements which is going to
be better served by grouping the data together in the correct layout/format
first and then apply-templates to the resulting temporary tree. Let me know if
the following concept is what you are ultimately attempting to accomplish...
<section-title>this element could be a title or a subtitle based on whether
there are any preceding sections who order of precedence is higher based on a
proprietary hierarchal data structure</section-title>
<section-title>If within the same "area" parent there is a preceding-sibling by
my same name then I should output as an "h2" element HTML heading tag. If I am
the first one then I should be output as an "h1" element tag.</section-title>
<section-title>Im the back-up title in case any of my older brother and sisters
lose their birth order or have been banished from the family all together for
deeds we won't mention on this family oriented email list.</section-title>
If the above is anything close to what you are trying to accomplish why not run
a first pass of "rules" that are in a separate and maintainable XML file and use
document order and structure to determine whether or not an element makes "the
cut". For example...
<c>better than foo!</c>
<e>i'm an independent</a>
could easily be pre-processed with:
These could be "woven" with a pre-processor that would match the ruleStructure
attribute value of each XML file and then use the structure of the matching
rules element hierarchal data structure to state:
"a" element is king if he maintains.
if "a" chose to entertain over maintain then "b" gets the gig, but if
"b" is out of the question then both "c" and "d" are going to have to do it
together until one of them decides to either give it up to the other or somehow
find a way to run things together peacefully. We'll keeps tabs on them and
change there priority appropriately.
"e" has always been responsible and loved by the family but ultimately is an
outsider. He gets precedence only if everyone else is out of the picture but hes
always going to be in the family picture even if a half shot of him leaning in
to get into the outside view of the lens is all he ever gets.
I realize this is a cheezy example but if the concept is even close to what you
are ultimately trying to accomplish as far as making document order and
hierarchal decisions as to what does and does not get processed then why not
utilize the vast capabilities of describing a HUGE amount of information with a
separate and easily maintainable hierarchal-based external rules file that can
pre-process the data to the point that in the end the only thing being output is
the absolute correct data using standard apply-templates to output things in the
correct hierarchal structure and be reassured that if a last minute change
shows up it will be taken care by one tiny hierarchal change or priority
increase or decrease and then use standard logic building templates and your job
is done. A combination of standard template rules, key elements and function,
and the generate-id() function and your 95% done...
Let me know if this "concept" helps things and I can help get you going on the
right track if necessary...
Best of luck!

This will do what you ask:
But I suspect there might be a better solution - I think it's
preferable to not select the nodes to process in the first place,
rather than select everything and use a no-op template to suppress
the things you don't want. You would need to give a little more
information for that kind of answer.
Thx for your quick answer.
Check the thread 'XSLT and FO/FOP workarounding' for details
of my problem -
maybe you know a better solution ;-)
My templates for now are:
<fo:table table-layout="fixed" width="100%">
But that does not work
1. The second element is there twice.
2. The xsl:use-attribute-sets="name()" does not work here.
