Topology Components as global TopoElements access

[Felipe Matas]

Hi, latot here, I was thinking in TopoElements, they are nice and well organized in the relation's table, but to me makes noise in the actual SQL use, because the TopoElement do not store any information about the to which layer belongs, so can be hard to use it safely.
So I thought, would be nice be able to use Components instead of TopoElements, with one little detail, Components + Topology_id.
Lets call it TopoComponent, the idea is that the element by it self can make reference to a Component of a TopoGeometry, at the same time how will have all the Component info + the Topology_id we can completely locate it in the database, this implies we can use Functions and Aggregate Functions without the need to specify the Layer_ID and the Topology Name or ID, everything could be checked when we work with it, including create a TopoComponent or remove it.
I think would be nicer use TopoComponents than TopoElements at least at user level.
Thx!
