Import doesn't make one schema define multiple namespaces. A processor is
not required to resolve or remember the schemaLocation of an imported
schema. Specify the schemaLocation for both schemas in your instance
document, e.g.,
xsi:schemaLocation='http://foo.com/namespace1 ns1.xsd
http://foo.com/namespace2 ns2.xsd'>

Subject: Schema validation using multiple schemas
> Hi All,
>
> I am trying to validate an xml file using multiple schema files using
> Xerces-J 2.5.0. The xml file specifies the location of schema#1 using
> schemaLocation. Inside of schema#1, schema#2 is specified using
> xsd:import. I get an error when the root element of the xml file is an
> element defined in schema#2.
>
> I have used the sample program dom.Counter that comes with Xerces-J
> 2.5.0, and get the error :
> [Error] test.xml:4:70: cvc-elt.1: Cannot find the declaration of
> elment 'ns2:report'.
> (I have tried using XML Spy Ver.5 Rel.4 and the DOMCount.exe of Xerces-C
> 2.3.0 but
> do not get an error.)
>
> Any help will be greatly appreciated. Here is the sample data I used:
>
> test.xml
> --------
> <ns2:report xmlns='http://foo.com/namespace1'
> xmlns:ns2='http://foo.com/namespace2'
> xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
