EAI — Terminal labeling constraints

Document: UML Profile and Interchange Models for EAI
Section: 8.3.2 (Transformers and Database Transformers) and others

Description:
Under the Constraints heading in Section 8.3.2 it states that "The input terminal must be labelled 'in' and the output terminal must be labelled 'out'." However, there is no constraint on the names of the terminals of EAITransformers in the metamodel (see Section 6.4.1.4).

(Similar constraints appear in Sections 8.3.3, 8.3.4, 8.3.5, 8.3.6, 8.3.7, 8.3.10, 8.3.11, 8.3.12, 8.3.15, 8.3.16 and 8.3.17 without corresponding constraints in the metamodel.)

Recommendation:
Unless there an overriding notational reason can be stated for requiring specific names for terminals, do not require names when they are not required by the metamodel. (Though it might be appropriate to recommend specific consistent naming conventions.)
