Well it's true we did'nt document the whole tags list,
but, from the 1.5 PostGIS documentation:
"GML 3.1.1 Simple Features profile SF-2 (with GML 3.1.0 and 3.0.0  
backward compatibility)"

So  GML 3.1.1 is supported up to Simple Profile level 2. (GML SF-2)
And TopoCurve is not inside SF-2, but should be part of topology  
profile.

Then it explains why your fragment is not currently supported.
