utype for STC region in SIAP query response

[Thomas Boch]

To illustrate my request, here is is how the STC-S FIELD is described in 
the query response of three different SIAP services :

Service 1 : <FIELD name="position_bounds" unit="deg" xtype="adql:REGION" 
datatype="char" arraysize="*">

Service 2 : <FIELD name="stcs" datatype="char" arraysize="*" 
ucd="phys.area;obs.field" unit="deg">

Service 3 : <FIELD ID="regionSTCS" name="regionSTCS" datatype="char" 
arraysize="*">

3 different services, 3 different ways to express the same thing.
Having a unique unambiguous way to detect the STC-S field would be very 
helpful for client consuming these services.
Cheers,

Thomas
