MHRA and Docbook XSL

Hi All,
     I just wanted to let everyone know that I have written up a first
crack at MHRA styling in footnotes for Docbook.  It took me a bit to
get back into the swing of XSLT but progress has been made.  I am not
sure if it is proper netiquette but I have attached a copy of the
current working version to my email.
     There are a few limitations at the moment.  Everything is linked
to the book tag at the top of the document and thus can only support
books at the moment.  This is because I couldn't use the ancestor axis
to match the linkend attribute of the biblioref tag to something in
the bibliography as the bibliography is not an ancestor (it is an
ancestral sibling).  I am casting about for ways to allow articles to
join the fun.  Also at the moment, the style only supports three types
of entries: books, journal articles, and articles in a book (called
incollection after BibTeX).  I will probably add other types of
entries as the need arises.  The last thing is that this only supports
output to XSL:FO, which means it only goes to PDF.  I will be working
on other formats once I have doing this in PDF down.
     Anyway, if anyone has any thoughts or feedback, I would be very
grateful to hear them.  Also, I can provide an example bibliography on
request.  Thank you very much for your time.

All the best,
Chris Yocum
