ebXML splits a message into two parts, a header and payload. The header
contains metadata
describing characteristics germane to the payload, if present or an
"activity". An ebXML message may contain a header only, this allows the
structure to be used for "acknowledgements", administrative functions (e.g.
pings) and RPC functions. The header may reference adjunct body parts
(fragments) within the message payload.

>b) there must be a root object that references all of the XML fragments

An ebXML header contains a manifest that describes all the parts (documents)
within a payload. An ebXML payload can contain any MIME media type,
including binary, XML, multipart/*, et al.

>c) images must be referenced with cid's within the XML fragments.

ebXML supports this today. An ebXML manifest contains "Document References"
that are specified using Xlink syntax. The document references refer to
CID's within the payload.
