HI Mark
Just for now:
From the vo-dml spec:
“Modelers SHOULD NOT use open ended multiplicities, i.e. with maxOccurs=-1, but it is not illegal in the current version of this specification. "
indicates it is not illegal to use non-fixed size data type instances. (not that I like them as you know)

The fact that you think you need it here may be due to an incompleteness in the model as I described in my previous email.
It may well be that the structure of the mapping, including explicitly representation of what-is-mapped-to-what, could make the need for an explicit indication of forward vs inverse redundant.
So looking forward to seeing more details of the model (and I can comment on another thread).

Cheers
Gerard


There are flavors which have open ended list of content
   Lookup table has open ended list of Entries
   Polynomials have open ended list of Coefficients,  to avoid individually modeling the different order of polynomial functions.

DataTypes are supposed to have fixed size.
