Met today and officially moved the XML over to svn, although PAB won't edit at all till next week; meanwhile, I'm fixing and constraining:

• The ODD file, which was huge and generic, is now much tighter, allowing only used elements, and including fixed valLists and Schematron to help editing.
• Inconsistencies in linking, ids, naming and so on have been fixed as a result of the much tighter schema and enhancement of diagnostics. Many improvements there.
• Began the process of changing full path links to prefixDefs; more to do there.
• Fixed XSLT and XQuery to take account of changes in markup to bring in line with 2018 TEI.

Next steps: Finish prefixDefs and processing implications, add more and fiercer diagnostics, add documentation for SVN to the ODD file, build ODD file documentation generation into the process, then train PAB with svn and hand back the process to her. The start writing the static build process.
