Error when <import> refers to a schema inlined in another XML document
----------------------------------------------------------------------
Key: XERCESJ-1100
URL: http://issues.apache.org/jira/browse/XERCESJ-1100
Project: Xerces2-J
Type: Bug
Versions: 2.7.1
Environment: Any JDK
Reporter: Arthur Ryman
The XSD spec states that the schemaLocation attribute of the <import> element
MAY point to a <schema> element that is contained in another XML document.
However, Xerces reports an error when the root element is not a <schema>
element. It should examine the full URL, including the fragment identifier to
identify the part of the document being refered to. This problem occurs in
practice in WSDL documents where <schema> may be inlined inside the WSDL
<types> element, both in WSDL 1.1 and WSDL 2.0. For example, we need imports
like this to work where the other schema is refered to via an id:
<xs:import
namespace="http://greath.example.com/2004/schemas/reservationItems";
schemaLocation="#items" />
We are attempting to make the Apache Woden WSDL validator fully spec compliant
and need the support in Xerces. Here is an example WSDL 2.0 document:
