Finally got around to adding HTML validation into the build process, and of course it threw up several types of error; a couple in XSLT generation, but most in encoding, especially nesting persNames (now disallowed by Schematron), and structuring tables. The HTML validator has nice feedback on the table structure, catching cases where the cell and row counts don't make sense. Fixed a whole pile of those sorts of issues, as well as one inconsistency in the taxonomy.
