A tabular listing of all tags used, and all non-default attributes and non-arbitrary value sets is now complete, viewable as HTML and XML . This is a good start.

The next stage is to create a sample document including all of these features, but realized in P5. This should include a complete bibliography with examples of all the main item types. We should also look closely at the DHQ Tag Zoo document to see if we can identify weaknesses in our P5 document type, and any document features we haven't covered.

I'll create tasks for this.
