SYSML2 — Incorrect production for attributes-compartment-element

The production for attributes-compartment-element is incorrectly referencing "UsagePrefix UsageDeclaration".

It should reference "UsagePrefix Usage".

Correct production for attributes-compartment-element

The intent of this issue was to remove DefinitionBody* from the production, but allow a ValuePart (i.e., a feature value in textual notation). However, the issue suggests doing this by replacing UsageDeclaration DefinitionBody* with Usage. But the production for Usage actually includes the UsageBody, with curly braces {...} for a non-empty body and a terminal semicolon ; for an empty body (see 8.2.2.6.2). This was not what was intended.

Instead, of Usage, the revised production should use usage-cp as added by the resolution to SYSML2-63. (If the resolution to this issue, SYSML2-62, is approved, but the resolution to SYSML2-63 is not, then the revised text for usage-cp from the resolution of SYSML2-62 shall be treated as part of the revised text for this resolution.)
