SSAP: PARAMs in GROUPs

[Igor Chilingarian]

Dear Markus, Doug, and all,

I'm a bit concerned about PARAMs as replacements of FIELDs in the
SSAP query response. In the examples given in the document there
are PARAMs within GROUPs, whereas FIELDs are referenced by FIELDref's
Though this is VOTable schema compliant, don't you think it would be
better to move all the PARAMs outside GROUPs and make them child elements
of the TABLE, and put PARAMrefs in the GROUPs instead?

Why it can be useful:
 * The meaning of the groups will become clearer
 * It will allow homogeneous handling of PARAMs and FIELDs in the software
   parsing the response
 * Since it is possible to put GROUP inside GROUP, the only way to locate
   all the PARAMs is to make recursive search over XML-tree, and it doesn't
   sound good -- it will not be needed if we move them to the root level
   of <TABLE>

With best regards,
						Igor
