The class 'GeologicSpecimenPreparation' is modelled as a feature or data type, but has at least one supertype of a different category. The supertype is ignored.
Context: Package 'Model::Domain Model::GeoSciML v3.2::GeoSciML::LaboratoryAnalysis-Specimen::GeologicSpecimen'
GeologicSpecimenPreparation has stereotype <> which makes it a subtype of AbstractFeature, but is also a subtype of specimen::PreparationStep, an association class which comes from O&M. It's either one or the other, but not both.
Fix to GeoSciML 3.2 ?
