TIP Model Validator ErrorConditions

The table summarizes part of the error conditions:

Target	Error Condition	Error Level	Comment
All kinds of artifacts	Class having 2 attributes with same name	Error	""
Entity	Entity inheriting from association class	Warning	Note that I think the import tool makes it already an association class artifact
Association Class	Association class inheriting from entity	Warning	""
