BSA — Precise definition needed

The document only indicates (by examples) how to code CORBA::TypeCodes
into stringified form used in metadata. We need much precise definition
how to do it and what to expect in 'type' tag of metadata.
Suggestion:
a) to investigate if such "rules" already exist in OMG worlds (such
as XMI), then clarify it in our document.
b) we may find that for sequences of IDL types defined in
DsLSRBioObjects module we will need to add also several sequence<...>
constructs in our spec (fortunately we have already quite a lot there);
this would be needed for being able to specify a "repetitive" argument -
when we do not know how many occurences it can have.
