Another small fix needed in WS-BaseNotification WSDL

[Steve Graham <sggraham@us.ibm.com>]

As reported by alain@isi.edu:

Looking at WS-Base-Notification, I noticed the text
says 
InitialTerminationTime (in a subscription input message) can be xsi:nil.
However the schema doesn't specify that it is a possibility.
it says:
                  <xsd:element
name="InitialTerminationTime" 
                    
          type="xsd:dateTime"
                    
          minOccurs="0" maxOccurs="1"
/>

instead of 

                  <xsd:element
name="InitialTerminationTime" 
                    
          type="xsd:dateTime"
                    
          minOccurs="0" maxOccurs="1"
                    
          nillable="true"/>


I agree with the suggested change.  Please
add this to the "appendix" of small items to fix in the XSD/WSDL
for WS-Notification.
