RE: schema imports

Title: Message

I don't know if this is useful to you but you can just import a file in the same directory as the WSDL.

 

  <wsdl:types>
    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
       <xs:import namespace="foo" schemaLocation="foo.xsd"/>
    </xs:schema>
  </wsdl:types>

Thanks for the reply -- but when we get to dealing with imports -- you resolve down to having to actually publish the schema at some URI for reference -- something I was hoping I could avoid.  I wish there was a handy way to reference other schemas defined in the types section, but alas, I've yet to find a way to pull this off.

Hmm, this appears to be one of the more vague areas of the WSDL spec.  WSDL1.1 is very vague about schema use (in fact doesn't explicitly say targetNamespace is required, when it really is in practice), and WSDL1.2 is clearer, but still a little ambiguous.

The following ref from WSDL1.2 seems to imply that a schema "embedded" in a WSDL should be a valid standalone schema that has been copied into the types section:

3.1.2 http://www.w3.org/TR/wsdl12/#embed-xsd

If you believe that implication, then your schema below is not a valid standalone schema because it references an external (to itself) schema that it does not import.

While this may work for some WS toolkits that handle more questionable gray areas of the specs, your best bet for interoperability would be to follow the spec more closely and use valid standalone schemas for embedded (in the types section) wsdl schemas, and use nested imported (see 3.1.1 of that same WSDL1.2 spec above) schemas for the externally defined types that those embedded schemas reference.  http://www.w3.org/TR/wsdl12/#import-xsd
