Hi

You are beyond the core consensus of the OCL specification...

OCL is UML aligned but has no support for generic types as such; though
what is a Set(T) if not a generic type? Conversely UML has no support
for nested types although Set(Tuple{...}) is used by the OCL spec.

Creeping support in Eclipse OCL means that what you want is increasingly
supported.

You should find that the current pivot-based Eclipse OCL (M4 release on
Wednesday) should allow you to use Sequence(Sequence(Real)) as a
property type. The Kepler M4 relrease should be installable on Juno.

Regards

Ed Willink
