1. In p7tpl.owl there are specializations of proto-templates from classes: dm:Relationship, dm:ClassOfRelationship and dm:ClassOfClassOfRelationship.
Ontological correctness of these specializations is doubtful. Probable it'll be better to remove them? They do not really add any semantics to the model
2. Some proto templates are declared subclasses of ProtoTemplateStatement, but not all of them #ClassOfCompositionOfIndividual is not declared ProtoTemplateStatement, for example.
