[postgis-users] topology : statue of topogeom composition?

[Rémi Cura]

Hello everybody.
a question mostly for Sandro I'm afraid.

What is the current status of postgis topology regarding composition
between topogeometry?

First of all is it possible to have topogeometry composed of other
topogeometry, themselves composed of other geometry, and so one?

Second,
if this is possible, are this kind of topogeometry properly maintained when
there is a change in the low level topology (splitting an edge for
instance).

I think I know the answers,
but I really would like to be sure.

Thanks =)

Cheers,
Rémi
