This isn't my understanding, or at least it is only one possible
interpretation. I would take it as a given that it is unacceptable to
require xsi:type on every element. This is hardly likely to encourage
adoption of UBL.
 
Hence, UBL document types should reference UBL types/element in their
content models. If you want to use the ur-type of a type, you need to
use the ur-type of the document type as well. In this way you put the
onus on the ur-type users, which seems appropriate since they are likely
to be the minority.
