StandardsRegExt, schema change

[Ray Plante]

Hi RWGers,

Officially, the RFC period for StandardsRegExt ends May 14 (see
http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/StandardsRegExt10RFC);
however, we'll probably keep it going to a little past the Interop meeting 
next week.  Then it will be on to the TCG review.  

We did get one set of good comments so far from Mark Taylor, and I thought 
I would highlight one recommendation that Mark made that the authors agree 
with.  It's minor, but it does actually require changing XSD schema file.  

Section 3.1.1 indicates how, when describing a standard, one can indicate 
the "endorsedVersion" of the standard.  This element includes an optional 
attribute, "status", with controlled values: "rec", "prop", "wd", and 
"n/a" (for Recommendation, Proposed Recommendation, Working Draft, and not 
applicable).  To match current usage in the IVOA, we want to change "prop" 
to "pr".  

I don't believe that there are any instances using the posted 
StandardsRegExt schema out there in the wild, and even so, such a change 
is likely to have very little impact; nevertheless, if anyone is aware of 
an actual use of the schema that might be affected by change, note it to 
the list.  

cheers,
Ray
