I've tweaked the XSLT so that bibl is now acceptable in place of biblStruct, making the markup of bibliographies (and the maintenance of the biblio rendering code) much simpler. This is working for both XHTML and PDF rendering, in the /apa/ rendering pipeline. I still need to look at NLM output code. I've marked up a few items in the first article, and also tested the popup biblio references.

I haven't yet migrated the changes to the main site.
