XMSG

XMSG or "XML Messages" is a specification for using XML to send messages that contain a set of XML documents, embedded non-XML data, and references to non-XML documents in a fashion that supports scalable transactions and operates on a participant model.  This specification was designed to provide the ability to transport multiple documents and references to associated data objects within a single document (a "message") and preserve their identity.  XMSG will  provide the ability to associate metadata with both the documents and the message without modifying the original document or schemas for those documents.

XMSG was posted as a W3C Note on October 13, 2000 by  Lexica, LLC.  It is based on the basic principle of providing a simple way to transport multiple XML documents within one logical XML construct without dictating any layered semantics of a messaging protocol that might be layered on top. The general philosophy is to provide the general structure upon which messaging protocols for specific business or technological purposes can be layered allowing the identification of that messaging intent but not dictating the exact syntax and semantics of the subject message.
