Final technical agreement sought for EXPRESS 2

[Wilson, Peter R]

Phil,

    You seem to be reviewing a different version of Ed 2 than I am. I'm looking at the version with change marks that Jochen emailed on 28 March. In this the first paragraph of clause `G.4.3 Secondary population' describes a global rule for maintaing REFERENCE semantics.

    Personally, I think that due to the artificial constraints put on the use of USE and REFERENCE by Yang/Danner that first/second class distinctions are moot in STEP models. Don't have any such global rules in the mapping. In other words, I was dissapointed to see the gloabl rule in the algorithm.

    Regarding comments, I strongly urge that any comment mapping be left to implementors of the algorithm, and they should ignore all comments. A comment is a comment is a comment and is white space as far as any EXPRESS processor is concerned.
