Hi Doug,
It's difficult because I suspect that clients would have a preference... 
However, we need to allow the minimal compliant implementation to be as 
simple as possible,  Having to generate a reference to the WSDL might be 
more challenging for an implementation in order to be ws-mex compliant 
(e.g. in case of a firewall).    So, I think my preference would be - keep 
it simple for the sake of the minimal requirements to ensure compliance. 
Perhaps recommend that the WSDL is inlined if possible (as you state). 
It's not great for the client to have the possibility of an extra MEP, but 
not a showstopper as it can still get the WSDL.

Re: mex.GetWSDL question

Yes if we added the attribute I would want "inlined" to be the default - 
I'm just not sure if we're adding good optionality or unnecessary 
complexity  :-)   Our constant struggle.

Re: mex.GetWSDL question

How about if we add the attribute to allow you to specify the form of the 
data with the default being 'inlined'. 
All the best, Ashok

I'm working through the testcases for MEX and I have a question about the 
GetWSDL operation.  Right now GetWSDL acts much like the old GetMetadata 
operation did in that it is up to the service to decide which form to 
return the metadata in - inlined, URL or EPR.  Now that GetMetadata allows 
the client to optionally ask for the metadata in a certain form, I'm 
wondering if we should allow the same option on GetWSDL.  So, perhaps 
something like: 
       <GetWSDL Content="xs:anyURI"? > ... </GetWSDL> 

Another option would be to be a bit more prescriptive about it and require 
the data be inlined if available, and a URL or EPR only be returned as a 
last change kind of thing. 

I'm inclined to keep it simple and not add the optional Content attribute 
but then I do think we need to push people towards the "simple" response 
as well, which means inlining the data.  If enough services choose to 
always return a reference (e.g. http://www.example/stockQuote?wsdl ) then 
clients might get annoyed with not having the option of "just asking for 
the darn data" so that they can avoid the extra MEP.
