[tei-council] dataSpec content

I'm still poking away at my datatype replacement ticket ... We agreed that <dataSpec> should be used to fully specify a TEI-defined datatype and also noted in passing that its existing <content> child needed additional constraints (e.g, it shouldnt allow you to supply elementRefs) In fact it seems to me that the "content" of a dataSpoe should be much more restrictive: I'd like for it to contain just <alternate>, <sequence>, <valList>, or <dataRef>, with the additional constraint that <alternate> and <sequence>s it contains can contain only one or more <dataRef>s If no-one has any counterproposal that's what i am planning to try to implement anyway.
