1. A method of coordinating the transfer of documents from a first system to a second system, wherein each document includes document data and document attributes, comprising the steps of: forming a query in said first system which includes a list of document handling capabilities desired in said second system, wherein at least some of said document handling capabilities are based on said document attributes; sending said query from said first to said second system; determining in said second system the document handling capabilities of said second system and providing a response to said first system indicating whether said second system has said desired document handling capabilities; modifying said query in said first system, if said response is negative, to include a list of fallback document handling capabilities and repeating said step of sending said query and said step of determining the document handling capabilities of said second system; and repeating said step of modifying said query until said response is positive or until said list of fallback document handling capabilities is exhausted.
