Schema validation in 2.3.0 version

[Tosello Davide <Da...@LOQUENDO.COM>]

Hi all,
I am currently triyng to validate W3C VoiceXML documents under many XML validators.
The current schema has been validated without errors on Xerces-J 2.0.2, XSV 2002/01/11, 
IBM SQC 2.1.1 and XMLSpy 4.4.
Using the latest Xerces/J 2.3.0, I cannot parse the latest VoiceXML 2.0 Candidate 
Recommendation schema. Here is a simple "Hello world" VoiceXML:

<?xml version="1.0" encoding="UTF-8"?> 
<vxml version="2.0" xmlns="http://www.w3.org/2001/vxml" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:schemaLocation="http://www.w3.org/2001/vxml 
            http://www.w3.org/TR/voicexml20/vxml.xsd">
    <form>
        <block>
            Hello,world
        </block>
    </form>
</vxml>

The error message the SAX parser returns is: 
 
org.xml.sax.SAXException: Error parsing XML at line: 363, column: 72 of
http://www.w3.org/TR/voicexml20/synthesis-core.xsd. 
Error Message is: a-props-correct.2: Invalid value constraint value
'100.0' in attribute 'volume'
 
Since Xerces is a fully-conforming Schema parser, I would like to understand if there is a 
bug into Xerces-J/2.3.0 (other validators parse without errors) or if the synthesis-core.xsd 
needs to be modified.
 
Regards,
Davide
