Broken VOSITables-v1.0.xsd

[Mark Taylor]

Dear GWS,

the VOSITables-v1.0.xsd schema available from this (canonical) URL:

   http://www.ivoa.net/xml/VOSITables/VOSITables-v1.0.xsd

is currently (and probably has always been) broken.  It mistakenly
targets the namespace

   http://www.ivoa.net/xml/VOSICapabilities/v1.0

instead of

   http://www.ivoa.net/xml/VOSITables/v1.0

and this can cause validation problems.

This fact was mentioned as part of a larger issue in July by Markus
(http://mail.ivoa.net/pipermail/grid/2014-July/002633.html),
but not fixed back then.

This is clearly a document curation error, since the copy at
the canonical URL does not match the text in Appendix A.3 of the
VOSI 1.0 Recommendation
(http://www.ivoa.net/documents/VOSI/20110531/REC-VOSI-1.0-20110531.html).
The version in that appendix is OK.

Unless anybody comes up with a reason why not in the next few days,
I plan to ask the IVOA Document Coordinator to replace the existing
copy on the IVOA web site with a version cut'n'pasted from the
VOSI appendix, as per the attachment to this message.

Mark
