Hi Rahul,

I'm not an expert at IDC, and I'm not sure whether the case you mentioned
is a circular reference.

>From the description of {referenced key}:
"Required if {identity-constraint category} is keyref, forbidden otherwise.
An identity-constraint definition with {identity-constraint category} equal
to key or unique."

So "refer" on "keyref" refers to a "key" or "unique" component, not a
"keyref" component. Am I right?

I could be wrong. If you still think it's a circular reference, let me
know. Thx.

Hi,

If a keyref has a declaration:

<xsd:keyref name="ISBNnumber" refer="ISBNnumber">
...
</xsd:keyref>

then its a circular reference, which should not be allowed.

Please find attached a patch for the same.

Cheers,
Rahul.
