That is just a limitation of the DIG interchange language.
It does not support such restrictions.  I think there are plans
to change that for DIG 2.0, but I don't know how much progress
is being made on a new version.  There isn't much information
on the web about that.

The only way to overcome it is to use a different method
to communicate with Pellet.  I may be wrong, but I think that
the Protege interface only supports the use of DIG to communicate
with external reasoners.

The Swoop editor has a direct connection and should work, or perhaps
you would need to look for a programming solution to the problem.
