utype for STC region in SIAP query response

[Thomas Boch]

Hi,

Embedding a STC region in the SIAP query response is becoming more and 
more widespread, and we would like to support this feature in Aladin.
I would like to know if there is a standard (or de facto standard) utype 
to characterize the FIELD holding the STC region description.
Cheers,

Thomas
