Error parsing WSDL message

I have the following wsdl : http://pastie.org/804441 . I get the following errors with the wsdl. Im using it in a tool called XAware, which is a data integration tool.

This question is not about XAware. Just looking at the errors below and the wsdl file,does it indicate some problem with the WSDL im using or is my WSDL fine ?

Please help. Thank You.

The tool might be confused because the schema's assigning two prefixes to the "http://www.w3.org/2001/XMLSchema" namespace: both "xsd" in the root element:

xmlns:xsd="http://www.w3.org/2001/XMLSchema"

and the default (i.e., no prefix) in each "schema" element:

xmlns="http://www.w3.org/2001/XMLSchema"

Depending on how the software handles that case, it might be coughing on it. It's something worth fixing anyway, if for no other reason than it would make the WSDL easier to read.

<xsd:schema>

is better than

<schema targetNamespace="http://compservice.com" xmlns="http://www.w3.org/2001/XMLSchema">

It is my understanding that the <import/> statement must include a schemaLocation attribute. The import statement (if you truly need it) should look something like:

<import namespace="http://schemas.xmlsoap.org/soap/encoding/" schemaLocation="soapenc.xsd" />

It sounds to me like it might be partly an XAware issue/quirk, since as far as I'm aware, you shouldn't have to specify the schemaLocation of well-known schemas such as http://www.w3.org/2001/XMLSchema with a normally-behaving tool.

Perhaps you could try pointing the import location to http://www.w3.org/2001/XMLSchema.xsd and see what happens?
