Yes, you can do it in XSLT 1.0, but it sounds as though you need to
spend some time with the faq and the specs first.  You don't say whether
you have only one case of Category/@value and Subject/@value that you
want to group with, or whether either @value can have a variety of
values.  This impacts on the answers we can give here.

In general, to solve this kind of problem you can either use a processor
like Saxon, which provides an extension function called saxon:group, or
do more work with sorting, variables and RTF-to-nodeset conversion.
