In general I agree especially with that Document Type creator should not
be doing "manual optimizations". However I in the case of DOM to DOM
communication its possible to to much better than using XML text a content carrier.

In this case the question arises, where is the protocol interface ?
Is it an interface that accepts a arbitrary byte stream and transports opaque data
to a receiver (A) or is it a an interface that accepts a DOM tree and sends it
ot a receiver (B) ?

DOM  --> [streamifyXML] --> XML text -->[protocolInterface] -->something smaller,faster (gzip,
something smaller,faster --> [protocolInterface] --> XML text  ->[SAX] --> DOM

DOM  --> [protocolInterface] -->something smaller (gzip)
something smaller  --> [protocolInterface] -->DOM
