#32 Parser accepts invalid union?

[Uli Otto]

In psi/poi/attribute.ds there is the following union (comments left out):

union FeatureReference(FeatureTypeCode featureTypeCode )
{
NameBuildingBlockFeatureIndex nameFeatureId;
PoiPartitionCode poiPartitionCode;
};

Parse accepts it, but the semantic is not clear. We think that an error should be raised, if such unions are parsed.

Cheers,

Uli.
