WSE 2.0 SP1 unable to consume WSDL from DIME Specification

[Sebastien Tardif]

Subject: Web Services Enhancements 2.0 Service Pack 1 (WSE) unable to consume
WSDL from the WSDL Extension for SOAP in DIME specification

The WSDL Extension for SOAP in DIME specification can be obtained at this
URL:
http://www.gotdotnet.com/team/xml_wsspecs/dime/WSDL-Extension-for-DIME.htm

This specification includes a WSDL. This WSDL cannot be consumed by .NET
without an error message.

The error message is:
C:\ClientDotNetPrototype\CSharpTest\CSharpTest\Web
References\WebReference\Reference.map(1): Custom tool error: Unable to import
WebService/Schema. Unable to import binding 'SoapDimeBinding' from namespace
'http://example.com/DimeExample/Service/'. Unable to import operation
'PutCompanyInfo'. Unable to import binding 'SoapDimeBinding' from namespace
'http://example.com/DimeExample/Service/'. Unable to import operation
'PutCompanyInfo'. The attribute location is missing.

The same error happens without WSE, using only Microsoft .NET Framework 1.1
Version 1.1.4322 SP1.

It seems that WSE or .NET framework expect instead an illegal XML Schema:

Having this:
<xs:complexType name="ReferencedBinary">
<xs:simpleContent>
<xs:restriction base="xs:base64Binary">
<xs:attribute ref="ref:location" use="optional" />
</xs:restriction>
</xs:simpleContent>
</xs:complexType>

Instead of:
<xs:complexType name="ReferencedBinary">
<xs:simpleContent>
<xs:extension base="xs:base64Binary">
<xs:attribute ref="ref:location" use="optional"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>

After the modification using the illegal XML Schema we receive just a warning:
C:\ClientDotNetPrototype\CSharpTest\CSharpTest\Web
References\WebReference1\Reference.map(1): Custom tool warning: At least one
necessary import ServiceDescriptionFormatExtension has been ignored.

Now you my wonder why I say it’s an illegal XML Schema.

Because:
- XML Spy Version 2004 rel. 4 said: Schema error – undefined value for
‘base’ encountered – you must use a complexType instead of ‘xs:base64Binary’,
because a simpleContent/restriction can’t be based on a simpleType.
- Castor from: http://www.castor.org/xml-framework.html give same error as
XML Spy.
- As point out by this:
http://lists.w3.org/Archives/Public/xmlschema-dev/2002Oct/0031.html
- XML Schema specification from:
http://www.w3.org/TR/xmlschema-1/#ct-props-correct said: If the {base type
definition} is a simple type definition, the {derivation method} must be
extension.
- More recent work also confirm this constraint:
http://www.w3.org/TR/2004/PER-xmlschema-1-20040318/

What I expect from Microsoft:
- Publicizes this defect.
- Publicizes a Patch in the next two weeks.
- Includes the patch in subsequent service pack for .NET 1.0, .NET 1.1 and WSE

For completeness here the WSDL from the WSDL Extension for SOAP in DIME

So in resume your answer to my questions are:
What I expect from Microsoft:
- Publicizes this defect.
Microsoft answer: Make a wish.
- Publicizes a Patch in the next two weeks.
Microsoft answer: Make a wish.
- Includes the patch in subsequent service pack for .NET 1.0, .NET 1.1 and WSE
Microsoft answer: Make a wish.

Hum. Any workaround ? Are you confirming my understanding of the issue and
of your answers are correct?

Hello,

I have reproduced the issue with your code. This is a compatibility issue
for the DIME specification and may changed after many argumentation.
Therefore, I don't think there will be a fix soon. If this really impact
your business, I suggest you may submit a support incident to our PSS and
require a hotfix.

There has been some Known Issues Using WSE for DIME, you may refer to
following article:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwse/html/
wsedime.asp

If you have any concern, please feel free to let me know.

Luke

To be precise:
It's not a compatibility issue for the DIME specification
Instead:
..NET are not compliant with XML Schema specification and because of this
..NET is also not compliant with DIME specification. DIME specification comply
himself with the XML Schema specification.

Thanks Luke to have confirmed there is an issue.
