Thanks a lot for putting this out! What about a more explicit utype namespace definition such as

<VOTABLE

   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   xmlns="http://www.ivoa.net/xml/VOTable/v1.1"
   xmlns:ssa="http://www.ivoa.net/xml/SSA/ssa-v1.0.xsd"
   xmlns:sdm="http://www.ivoa.net/xml/SpectrumDM/sdm-v1.0.xsd"
   xmlns:stc="http://www.ivoa.net/xml/STC/stc-v1.30.xsd"
   xmlns:char="urn:vo-characterization"
   ...
 >
...
<FIELD utype="ssa:Access.Reference" ... /> <FIELD utype="stc:AstroCoordSystem.CoordFrame.PositionAngle" ... /> ...

It's clear that these utype-pseudo namespaces aren't real in the XML sense, however, an IVOA registry validation tool could still perform a consistency check against the proper versions of Schema with only little additional code to be added. Note that in above example model items are 'borrowed' from other data models (e.g. stc:AstroCoordSystem.CoordFrame.PositionAngle).

Cheers,
Markus

p.s. I know this is also a votable-, dm-, etc. -issue but given that subscription overlaps to a high degree I refrain from annoying recipients with multiple copies that such a x-post would generate. Received on 2007-01-26Z16:44:48
