Keep existing gml:ids on Geometries

[thorsten-reitz]

When a geometry already has a gml:id (through the alignment or because the geometry was copied unchanged), that ID should be kept and not deleted or replaced. The reason is that especially in CityGML, geometries are re-used by reference. If this would break backwards compatibility, this should be added an an option to all GML/XML writers.

Is this potentially a side effect of CityGML still using GML 3.1.1 for its Geometry model?

Clarification: While I still think that this should be considered as a proper solution, there is a workflow solution:

In the geometry rename, add the parameter "Copy Geometry Objects in Structural Rename", and set it to false, while setting the "Structural rename" paremter to true:

In this way, hale will copy the geometry literal instead of the object structure, thus bypassing encoding.

I had misunderstood this parameter to work exactly in the other way (i.e, it needs to be added, but set to true). Maybe we should rethink the explanation/value of this parameter :).
