Hopefully by now you've seen the below response from Fadi Maali on 
behalf of the GLD WG.  We apologize for the delay in sending it.   Does 
Fadi's explanation make sense and resolve your comment?  Procedurally, 
we need to record whether comments have been addressed, and let 
dissastified commenters know they have the option of raising a Formal 

Thanks for your interest in DCAT and your review of the specification.

However, this problem was considered out the scope of DCAT because of design choice  to have a minimal focused vocabulary and due to the available time/resources. Notice that DCAT makes no assumption about the dataset format or content. As you mentioned in your email, there exists a number of properties that can be used for particular datasets as void:vocabulary and I think there is some efforts in schema.org and elsewhere to describe schema of CSV datasets. However as I mentioned above, given the scope (and the resources) of DCAT, the schema description is not addressed.
