Tsach,

No, you can not legally use sets to influence the contents of the record.

One thing to remember is that GetRecord does not take the "set" argument,
so record X would have to belong to sets A & B (which is fine), but when
you do:

?verb=GetRecord&metadataPrefix=oai_dc&identifier=X

there is no way to specify if you want "thin" or "thick" oai_dc version of
X.

go ahead and create separate metadata formats to handle this situation.

Michael
