This means that the first constraint in 7.4 of the RNG spec is not 
satisfied.

http://www.oasis-open.org/committees/relax-ng/spec-20011203.html#interleave-restrictions

The motivation for this restriction is to make implementations easier.  In particular, 
it helps implementation of data binding tools and boolean operations.

How about changing <interleave> with <group>?

Cheers,
