Description of the proposal: Make IfcLoop and IfcVertex entities abstract.
IfcLoop
IfcVertex
They do not possess any attributes, therefore I don't see any reason to see them in a physical file. E.g.:
90 = IFCLOOP();
Therefore: make them ABSTRACT.
ABSTRACT
What do we win: clearer schema.
What do we loose: nothing.
Schema impact: backward compatible, I would even suggest updating the old schemas as well.
Instance model impact: No chance to submit a file with entities like IfcLoop and/or IfcVertex.
Backwards compatible: Yes.
Automatic migration possible: ?
Additional implications: ?
