Does the specs allow making conrefs from topics to maps?

Dear DITA TC,

This all started here:

The question would be if from a DITA topic I can make a conref to an 
element defined in a DITA Map, the particular example discussed in the 
forum thread is about reusing indexterms.

The DITA 1.2 specs states:

> http://docs.oasis-open.org/dita/v1.2/os/spec/archSpec/conref.html

>     When pulling content with the conref mechanism – if the referenced element is the same type as the referencing element, and the list of domains declared
> on the domains attribute in the referenced topic or map instance is the same as or a subset of the list of domains declared in the referencing document,
> the element set allowed in the referenced element is guaranteed to be the same as, or a subset of, the element set allowed in the referencing element.


I checked and the @domains attribute of the DITA Map seems to be a 
superset of the DITA topic @domains attribute. From what the specs says, 
in order for a conref from a topic to a map to be considered valid, the 
map domains should be a subset of the topic domains in order for a 
conref from a topic to a map to be considered properly valid.

So what's your opinion on this?

Regards,
Radu
