E2 to E1 SHTOLO test files

Tue May 7 11:55:09 EDT 2002

Jochen,

    I had a discussion at Myrtle Beach with Phil Spiby on the question of
putting the language_version_id before each schema. As far as I remember,
Phil said that the assumption was that the entire EXPRESS model would be in
a single file and that the language_version_id applied to the file. In other
words, the syntax production applies to a file. The IR53 model is in several
files, and hence the multiple occurrences of the language_version_id. The
LRM makes no mention of file(s) containing EXPRESS code.

    What happens if a model is partly Edition 1 (e.g., the traditional IRs)
and partly Edition 2 (e.g., new IRs like 52 and 53)?

    I think that a language_version_id should be associable with an
individual schema, not just with this unexplained concept of a file. If you
like, change the syntax production to read:
syntax = [ language_version_id ] schema_decl { [language_version_id ]
schema_decl } .

Regards
Peter W.

PS. I have not yet had a chance to look at Phil's latest list of issues to
see if this is in there or not.

PW: More properly stated, it is before the SCHEMA analysis_schema
PW: declaration (which happens to follow the product_analysis_schema).
