Thanks Stephan, you are right. However the current problem is that it is
not consistent with DM.

I have been looking further, and there are other properties where we have
a union in the domain (e.g., qualifiedInfluence, wasInfluencedBy,
atLocation). In
these cases the properties would have an empty domain in DL. I think that
it's better
to have it empty rather than allow inconsitencies with the DM.

Thus I still propose to make the change to the documents. Thoughts?
