GML or WKT in GeoSPARQL

Hello,

The GeoSPARQL standard allows for two ways of representing geometry: GML 
or WKT. I have always thought WKT to be the preferred format, because of 
its greater simplicity and its wider software support. But now I have 
discovered a drawback of WKT: It does not seem possible to control 
coordinate precision when transforming geometry to WKT in PostGIS. 
Unlike the function ST_AsGML(), the PostGIS function ST_AsText() does 
not have a parameter /maxdecimaldigits/. This can cause data to be 
bloated as well as erroneous.

What do you think?
Would it make sense to investigate the pros and cons of WKT and GML for 
serialisation of geometry in this group?

Regards,
Frans
