I am not sure how to do this, or if it can be done.In can be done with RELAX-NG:element PARTY {  (   (    attribute type { "lender" },    ...   ) |   (    attribute type ( "seller" },    ...   )  )I hope this helps.. . . . . . . . . . Kenp.s. given your example attribute values, are you perhaps trying to re-invent business documents such as invoice, purchase order, etc?  If so, you
