Description Katy Warr 2009-10-23 13:36:19 UTC
A GetMetadata request may return multiple documents all of the same dialect.  How does the client know which of these documents is the 'root' document?

For example (this is a side note mentioned in 7912):
When multiple WSDL documents* are returned from GetMetadata, how do we
distinguish the 'real' one - i.e. the one that would be returned from HTTP GET
targeted at <endpoint>?WSDL ?  

Note that there might be >1 root documents - for instance, in the case of one WSDL for soap 1.1 and one for SOAP 1.2.

*Multiple WSDL documents may be returned if operations are implicitly defined (via policy) or if WSDL documents are imported.

Here is a starting proposal:

Add an attribute @root to the dialect in order to indicate that the metadata section is a 'root' one.  Define the meaning of the 'root' document for each dialect.  

  <mex:MetadataSection Dialect='
  <mex:MetadataSection Dialect='

Comment 2 Robert Freund 2009-11-05 21:20:23 UTC
Use case is to allow the mex metadata consumer can determine if a wsdl document is intended to be treated as implicit.
I.e, that it is feature wsdl

Comment 3 Robert Freund 2009-11-05 21:21:22 UTC
proposed way forward: as part of definition of wsdl dialect in mex spec, we define an optional boolean attribute, called @isImplicit, which if present with value true indicates that this is feature wsdl implied value is 'false'
