Circular IDs and IDREFS.....need help!

[Madhav Lakkapragada]

Looking for easy help............
Can we have circular IDREFs in an XML File?
Example:

<A ID="N1">
   <Parent ID="N11" name="firstChild1" GrandChildRefs="#N21 #N22"/>
   <Parent ID="N12" name="firstChild2" GrandChildRefs="#N31 #N32"/>
   <GrandChildren name="thirdGeneration">
       <Child id="N21" name="abc" parentRef="#N11"/>
       <Child id="N22" name="def" parentRef="#N11"/>
       <Child id="N31" name="ghi" parentRef="#N12"/>
       <Child id="N32" name="jkl" parentRef="#N12"/>
  </GrandChildren>
</A>

The Parent element has references to Child element id's and the Child element has references to the Parent element id.
Any issues with such a circular referencing
Thanks.

Is there a DTD to validate this against?
"#N21 #N22" isn't an IDREF. It's just a string.

"#N21 #N22" isn't an IDREF. It's just a string.
Yuck.... . Maybe thats my problem.
When I load my XML file, it gives me an error
saying "Invalid datatypes for xsd:IDREFS".
I need to go back to some fundas here....whereeee is that Bible...
Thanks.
