Error resolving s:schema in a schema

28 May 2004 18:25:23 -0000

Xerces users and developers,
 
I have a schema that references the "schema" element in the http://www.w3.org//2001/XMLSchema namespace.
Notice the element in the sequence that references the "schema" element.
 
<s:schema elementFormDefault="qualified" targetNamespace="http://foobar.com">
      <s:element name="GetFooBar">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="0" maxOccurs="1" name="GetFooBarResult">
              <s:complexType>
                <s:sequence>
                  <s:element ref="s:schema" />
                  <s:any />
                </s:sequence>
              </s:complexType>
            </s:element>
          </s:sequence>
        </s:complexType>
      </s:element>
 
</s:schema>
 
I have a few questions:
 
1) Is it necessary to include an import statement with the following?
 
2) If so, why?  It appears that the Xerces parser can resolve other elements defined in the "XML Schema for Schemas" such as string, boolean, etc. without the import statesment.
 
Without the import statement, I am currently getting the following error:
 
Error src-resolve.4.2: Error resolving component 's:schema'. It was detected that 's:schema' is in namespace 'http://www.w3.org/2001/XMLSchema', but components from this namespace are not referenceable from schema document 'http://xxx'. If this is the incorrect namespace, perhaps the prefix of 's:schema' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'http://xxx'.
