UAF13 — 7.3 DMM Legend - 'External Type' Shouldn't Be Present in an Agnostic Spec (the DMM is Not a UML Profile)

7.3 Domain Metamodel Diagram Legend - Figure 7:3 Legend of color codes for element types defined in UAF

This shows 'External Type' defined as 'An External Type is an element that exists outside of the core DMM but is referenceable by elements in the DMM'

1) Consistency - What is a type? The term 'element' or metamodel element' is used

2) There should be nothing external. The DMM is agnostic. It is also not a UML profile. it is not a SysML profile. The purpose of the DMM is to define an abstract metamodel (complete) and the ISO 42010::architecture viewpoint content using these metamodel elements.
