that has a srsName. Due to the way that AIXM is modelled, this can only be one of the following:¿
- aixm:Surface
...
- aixm:Curve

- aixm:Point
If no such ancestor is found, that geometry without srsName derives its CRS from the srsName of the gml:Envelope in the boundedBy element of the feature or feature collection in which the geometry is contained. Geometries for which no CRS can be derived are invalid.
