Subject: New Issue: WS-Discovery - Editorial - Remove wildcard from the
normative outline descriptions

 

Issue

The normative outline for the Discovery messages describes
uses XPATH like syntax to describe various elements of the message. This syntax
uses wildcard in the description of few of the elements. Here is an example of
such path from the description of Hello message:
/s:Envelope/s:Body/*/d:MetadataVersion. The wildcard here is unnecessary and
may unnecessarily define the MetadataVersion element in other parts of the Body
(including extensions) as well.

 

Proposal

Replace the wildcard with exact path. This results in the
following modifications in the spec.
