Three still fail, but substantial progress. The to-husql-queries
tests are failing much worse, but are not a current target (nor is
the validator, frankly, but it irks me that it is so broken)
Failures are to do with XML elements with (legitimate) text content. My validator - specifically I think the function adl.validator/disjunct-valid? - is causing spurious validation fails. But just having a battery of unit tests is progress.
