Description Ed Willink CLA 2021-05-28 09:30:09 EDT 
With may-be-invalid analysis the null-by-default multiplicity is a real pain.

The OCLinEcore serialization culd be changed to default to [1], just like UML, but unlike Ecore, in text witjput affecting Ecore.
Comment 1 Ed Willink CLA 2021-06-02 00:14:48 EDT 
The OCLinEcore tutorial states that OCLinEcore follows UML rather than Ecore default multiplicity.

For *.ecore a change is not really a problem since the *.ecore setting is definitive; it's just a matter of which polarity is implicit in textual form.

For Complete OCL (or OCLinEcore) source the default seems to guarantee may-be-invalid. Really tedious for Complete OCL tests.
Comment 3 Ed Willink CLA 2021-07-06 02:45:12 EDT 
testLoad_Bug402767_oclinecore written in 2013 tests for the original 'UML' behaviour.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=464927#c5 motivates the change for maximum compatibility in 2015.

Since [1..1] is potentially breaking we will need a preference.
Comment 4 Ed Willink CLA 2021-07-12 11:42:37 EDT 
Preference with changed default pushed to master for M1,
