[tdwg-content] Can all DwC be Simple DwC?

It may be worth teasing out the boundary of what can/cannot be
represented via simple (i.e. flat) Darwin Core. Auxilliary terms (which
comprise the classes "MeasurementOrFact" and "ResourceRelationship") are
currently left out of Simple Darwin Core. The DwC Terms Quick Reference Guide  states:
"The terms found under the Auxiliary Terms section can only be meaningfully implemented in an
application that supports relational structures".
The Simple Darwin Core reference  explains "Every field in the Simple
Darwin Core may appear either once or not at all in a single record - otherwise how could you
distinguish one 'scientificName' field from another one?"
Couldn't this be addressed using subscripts? E.g.
(There is precedent for subscripting rdf properties:
Allowing this would increase the types of data that can be exchanged via
spreadsheet. It would also have the virtue of
permitting a single DwC standard, which would help to lesssen
confusion amongst potential adopters. (The existence of a "Simple Darwin
Core" seems to imply that "regular Darwin Core" is not simple.) Are
there reasons not to do this?
