I think, this is behind the TMQL specification. TMQL specifies the
grammar and to some extend the model (sequences, tuples etc.) and the
mapping to TMRM. Whether a 'classical' Topic Maps engine or any other
data source, i.e. an IMAP4 account, is queried, is irrelevant for
TMQL. And the (virtual) mapping to TMRM/TMDM of the external data
source (i.e. the e-mails) to topics etc. is also irrelevant.
TMQL simply assumes that it operates upon TMRM/TMDM.

In my opinion the current draft is sufficient (mandating sequences,
tuples and TMRM mapping), nothing more is needed here.
