All files are now converting, so I've added the validation step, which is throwing up lots of new errors in the SGML as well as odd combos my XSLT needs to account for. I'm beginning to realize that a second pass over the TEI, to add desirable features such as line tagging, would be a very good idea. Speeches containing ab elements with linebreaks, and even worse, stanzas with no lines, are a bit of a sad result.
