Ouch.  Yeah, that's bugs (which fortunately didn't hit at least my
RegTAP services because of fortunate conincidences).

That is right.

Sure: Dear registry operators, please make it a routine to run your
registries through the validator at the beginning of each month.

However, this particular problem doesn't concern too many operators.
VizieR, where most of this comes from, will have a shiny new
publishing registry real soon now (cf. the talk at the last interop),
so that problem is going to go away by itself.

Then I'm spotting ivo://xcatdb/3xmmdr7/tap, which is produced by you
and should be easily fixed (use the opportunity to fix the
broken xsi:schemaLocation on this one), and likewise
ivo://ia2.inaf.it/tap/projects (though the schemaLocation is fine in
this case).  It might be interesting to understand where the bad
namespace URIs came from.

Finally, there's ivo://mast.stsci/ssap/befs served by STScI.  I'm
sure Theresa can quickly fix this one.

So... phewy... it's essentially three records plus something that's
already fixed with the rollout of the fix pending.

Thanks for bringing this up,
