Multihop routing function

Hello,

The ebXML Messaging TC is working on a profile of ebMS 3.0 for multihop
messaging.  This profile refers to a "routing function" that intermediaries
use to forward message through an I-Could based on the rich metadate
provided by the ebXML business document header.  Attached is an experimental
"ebRouting" schema that reuses elements and types in the draft CPA 3.0
schema to express such a routing function.  The core idea is that the
parameters which, in a multihop path, need to be specified separately for
each hop, are neatly grouped in the cpa3:Transport element. These include
protocol, endpoint details, MEP binding, transport security.  The schema
links these to pattern selection expressions, expressed as Xpath
expressions.
