This is perhaps more appropriate for xml-dev and I've crossposted the reply.
JUMBO is trying to track the spec as it evolves. At present it supports TEI
pointers before the last draft (i.e. with spaces) but I'll hack in the
commas tomorrow. As far as I know it behaves as the spec, but I's really
like some torture tests to see no only if it parses properly but also
performs properly. (The msg from James Clark shows that certain elements
might not be found or that there is ambiguity in the spec (e.g.
does *IMPLIED match *). For myself I find it easiest to have real examples
to develop code against and then when that is done, the authors can match
against the code.
