Description

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.
