Is there a xsd file for "http://schemas.microsoft.com/2003/10/Serialization/" namespace?

Question

I want to create / infer schema for data-contract serialized classes.

When I use [DataContract(IsReference = true)] attribute the serializer is injecting attributes z:Id="i2" and z:Ref="i2" to reference the same object instances.
Both attributes are from http://schemas.microsoft.com/2003/10/Serialization/ namespace.

Questions:

• Is there a xsd schema file for the namespace used by serializer which I could import into my schema?
• For now I am defining those attributes as a xs:ID / xs:IDREF pair. Is that correct?

Thanks in advance.

Answer 1

The xsd schema is supposed to described here - look for the section Data Contract Serialization Schema. However, if you do look for your attributes, you will not find them in there - documentation bug!

To get the full schema, take a look at this and this - inside the WSDL types, you'll find the correct schema. As for your assumption regarding the attributes, yes, you are correct.

I am inlining it here, just in case:
