Subject: Re: FW: Latest Specification document

One other consideration is to hold back on the use of <ebXML> and
think toward something like <ebXMLHeaderEnvelope> since our
current direction is in multiple parts and not one document . We should
consider that at some future point <ebXML> may make sense as a top tag for
pure XML approach, which would then include <ebXMLHeaderEnvelope>.

(and do we have a position on imposing any top element on the
upper level business content?, if so we should consider

This would be a much better approach (IMO) than
use of PIs or a single, required root element
tag such as <ebXML> especially given that
there will be separate documents (header
and payload at least, possibly others). See
John I's message.
