The datatypes changed from 
"http://www.w3.org/TR/2002/WD4110xquery-operators-20020816#dayTimeDuration";

to

"http://www.w3.org/2001/XMLSchema#dayTimeDuration”;

as W3C renamed the identifiers. That's why the function definitions had
to change

Simple example: A subject Alice asks for read and write permissions on a
file R. The multiple decision request according to section 2.3 of the
profile would be (simplified identifiers):



<Request> 
  <Attributes Category="access-subject">
    <Attribute AttributeId="subject-id"> 
       <AttributeValue DataType="string">Alice/AttributeValue>
    </Attribute>
  </Attributes>
  <Attributes Category="resource">
     <Attribute AttributeId="resource-id">
        <AttributeValue DataType="string">R</AttributeValue>
     </Attribute>
  </Attributes>
  <Attributes Category="action"> 
     <Attribute AttributeId="action-id">
        <AttributeValue DataType="string">read</AttributeValue>
     </Attribute>
  </Attributes>
  <Attributes Category="action"> 
     <Attribute AttributeId="action-id">
        <AttributeValue DataType="string">write</AttributeValue>
     </Attribute>
  </Attributes>
</Request>


Hope it helps,
