Issue with XSD 1.1 assertions with dateTime and duration...

[Jorge Williams]

Hey Guys,

I'm working off of the latest 1.1 branch.  I have the following schema:

<schema
    elementFormDefault="qualified"
    attributeFormDefault="unqualified"
    xmlns="http://www.w3.org/2001/XMLSchema";
    xmlns:xsd="http://www.w3.org/2001/XMLSchema";
    xmlns:tst="http://www.rackspace.com/test/simple";
    targetNamespace="http://www.rackspace.com/test/simple";>

    <element name="test" type="tst:Duration"/>

    <complexType name="Duration">
        <attribute name="start" type="xsd:dateTime" use="required"/>
        <attribute name="end" type="xsd:dateTime" use="required"/>
        <assert test="xsd:dateTime(@end) le (xsd:dateTime(@start) + 
xsd:dayTimeDuration('P1D'))"/>
    </complexType>

</schema>

Essentially, I want to make sure that the duration between start and end is not 
longer than one day.  I test against two documents (using options -fx and 
-xsd11  on the CLI validator):

good.xml

<test xmlns="http://www.rackspace.com/test/simple";
      start="2012-03-12T11:51:11Z" end="2012-03-13T11:51:11Z"/>

this document should validate.  And 

bad.xml

<test xmlns="http://www.rackspace.com/test/simple";
      start="2012-03-12T11:51:11Z" end="2012-03-13T11:51:12Z"/>

which should trip the assertion.

Unfortunately xerces fails both documents, which looks like a bug to me 
especially since Saxon passes good.xml but fails bad.xml.

Thoughts?
