I don't have enough experience with all of these to make an informed 
comparison.

Well, as you said: RDBMS with XML support can really do both - tables 
and structured documents.  I haven't seriously worked with XML feature 
in RDBMS to judge fitness of this approach.  It does seem to be a 
general approach to include non typical data types into RDBMS so there 
seems to be some need for this in the market - or at least vendors 
believe there is.
