Re: <include> with XSV (web-version)

Hi all,

I'm also experiencing validation problems with the new version of the web based
XSV validator. I just tried to validate the following simple instance and
schema:

Fields.xsd:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 <xsd:complexType name="fields">
  <xsd:sequence>
   <xsd:element name="field">
    <xsd:complexType>
     <xsd:attribute name="tag" use="fixed" value="15A"/>
    </xsd:complexType>
   </xsd:element>
  </xsd:sequence>
 </xsd:complexType>
 <xsd:element name="fields" type="fields"/>
</xsd:schema>

Fields.xml:
<fields xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="Fields.xsd">
 <field tag="15A"/>
</fields>

The files are located at http://www.allette.com.au/Demo/XSV/Test/ and when I run
the web based validator with the following address:

http://www.allette.com.au/Demo/XSV/Test/Fields.xml

I get the following error:

"No declaration for document root found, validation was lax
schemaLocs: None -> Fields.xsd
The schema(s) used for schema-validation had no errors
No schema-validity problems were found in the target

Schema resources involved

Attempt to import a schema document from
http://www.allette.com.au/Demo/XSV/Test/Fields.xsd for no
namespace, failed"

Since the import for Fields.xsd failed I suspect there is an error in this file
but I can't seem to find it. Any suggestions?

Cheers,
/Eddie
