They can. The "caveat" right now is that for most DwC predicates  
(object properties), doing will assert that the CDAO subject  
instantiates whatever the domain of the DwC term is declared as.

So if you apply dwcterms:catalogNumber to a CDAO subject term, you  
would implicitly assert (in addition to whatever CDAO asserts about  
it) that that subject term is an instance of dwcterms:Occurrence  
(because dwcterms:catalogNumber has domain dwcterms:Occurrence).  
Whether that's a problem or not, depends on the context I suppose.
