[oXygen-user] XML Schema validation and XInclude

[Robert Koberg]

Hi,

I have some XML Schemas that xs:import the xml namespace attributes 
(xml:base so I can use XInclude and be able to validate it). I am 
getting a validation error on the schemas themselves when I try to 
validate in oxygen saying they can't find the xml.xsd which is in the 
same directory as the import schema. Here is the error message:

Description: W schema_reference.4: Failed to read schema document 
'xml.xsd', because 1) could not find the document; 2) the document could 
not be read; 3) the root element of the document is not <xsd:schema>.
URL: http://www.w3.org/TR/xmlschema-1/#schema_reference

When I use JARV/MSV the schemas validate (and so does the instance 
document).

Is this a bug in oxygen or perhaps xerces? I am using oxygen 6.1 and Mac 
OS X.

(I have also tried using xs:anyAttribute with the xml namespace and 
neither oxygen or JARV validates the instance document.)

Here is a test schema and a xml.xsd:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
   <xs:import namespace="http://www.w3.org/XML/1998/namespace" 
schemaLocation="xml.xsd"/>
</xs:schema>

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
elementFormDefault="qualified" 
targetNamespace="http://www.w3.org/XML/1998/namespace" 
xmlns:xml="http://www.w3.org/XML/1998/namespace">
   <xsd:attribute name="base"/>
</xsd:schema>

best,
-Rob
