Hi Jeremy,

That's close to the idea, and the analogy to SVG embedding in HTML is good,
but let me try to clear up a few possible misconceptions.

- Our intent is to develop a single, standard MNX "body type" (or module,
if you like) for Common Western Music Notation documents, and that this
encoding would be part of the MNX standard -- in other words, neither a
recapitulation of MusicXML nor MEI's CMN module. We expect that this
encoding will incorporate ideas from multiple standards (see the "Something
Borrowed" piece of the post).

- Consequently, a container document is trying to do more than merely wrap
up MusicXML or MEI documents in their present-day form. However, that would
be actually possible and might even be useful.

- Note that container documents would normally provide lots more
information about each contained thing like bibliographic metadata, header
information, etc. So the stuff inside the container no longer has to bear
the burden of doing that.

Best,

.            .       .    .  . ...Joe
