> According to the spec, asserts are only allowed on group references, not 
> group definitions, however there is no warning when an assert is put on the 
> spec. In fact, the following test fails, which is not expected behavior. 
> There should we atleast a schema definition warning, rather than just 
> ignoring the assert.
