/**
 * Zaps the "Type" class to be non-abstract.
 * <p>
 * It appears that the UM L merge was any-non-abstract implies non-abstract, and that this has changed to any-abstract implies abstract.
 * The *.cmof content was irregular and so the change has an effect.
 * <p>
 * For Type, there is a problem in creating superclass proxies if Type is abstract, so force it non-abstract.
 * <p>
 * For DataType non-abstract is in use so preserve it for now.
