Should the 'interface' attribute of interface.wsdl point to the portTypeURI?

[ashok malhotra <ashok.malhotra@oracle.com>]

Currently the interface attribute of the interface.wsdl element points 
to the URI of the portType in the WSDL definitions file.
There must be a good reason for this.  I'm looking at writing functions 
to attach policySets to interface elements and it would
be better if the attribute pointed to the file itself.

WSDL 1.1 Element Identifiers: http://www.w3.org/TR/wsdl11elementidentifiers
specifies how to identify individual interface elements in a WSDL 1.1 
file using fragment identifiers following the URI of the definitions
file.  The following example is taken from that document.

Assume that the URI of the definitions file is: 
:http://example.org/TicketAgent.wsdl11

The URI for the portType is: 
http://example.org/TicketAgent.wsdl11#wsdl11.portType(TicketAgent)
Now, if you want to refer to a particular message you need tosay:
http://example.org/TicketAgent.wsdl11#wsdl11.portTypeOperation.output(TicketAgent/listFlights)
Construction the identifier for the message seems more complicated than 
if you started with the URI for
the file itself.

Example:
Consider WSDL 1.1 document located at 
http://example.org/TicketAgent.wsdl. Each WSDL 1.1 Element Identifier is 
shown in comments above the WSDL 1.1 element

 <!-- http://example.org/TicketAgent.wsdl11#wsd11.definitions() -->
