I can understand the argument being made but security has to extend beyond
mere data transfer.  The efforts and success achieved by ebXML in creating
"contractually binding" environment should not be compromised by lax
security at the application end.   My understanding is that we are
business semantics - not how to ensure persistence.

I took that as a given. However, as I indicated, it
really has nothing to do with "persistence on some
media". The fact that I use XML Encryption on a message
does not necessarily require any manner of persistence
(e.g. storage on some form of media such as hard disk).

The confidentiality accorded a message that is characterized
as "isConfidential='persistent' is a function of the message
itself. isConfidential='transient-and-persistent' is a
function BOTH of the communications protocol that is used
to exchange the message between two adjacent network nodes
and of the message itself, independent of the mechanism
used to convey the message between network nodes.

The fact that a message that has used a persistent form
of confidentiality *might* be stored (locally or elsewhere)
on some form of storage media is secondary to the definition
of what this property means.
