The Data Cube ontology is not OWL 2 DL in several ways and attachment 
declarations is certainly one of them.

However, I don't think punning is quite enough here. I believe the range 
declaration of qb:componentAttachment would still be problematic. So one 
would need to make qb:componentAttachment an explicitly declared 
annotation property anyway in which case you wouldn't need to depend on 
punning.
