identity constraint not declared

[popprem]

hi,
i'm getting a warning which says that identity constraint is not declared in the <keyref > tag.

Can any1 pls help?
thanks in advance.

part of the xml schema :-

<xsd:key name = "PK_CounterParty">
<xsd:selecter xpath =".//Counter_Party_CID"/>
<xsd:field xpath = "CompID"/>
</xsd:key>

<xsd:keyref name = "CounterParty_CPID" refer="PK_CounterParty">
<xsd:selecter xpath =".//Counter_Party"/>
<xsd:field xpath = "CPID"/>
</xsd:keyref>

just a note: ".//element" is a very strange xpath. do you mean "./element" (child) or "//element" (any element)?

<selecter> is not a valid Schema element (it's <selector>)

regards

This is my schema.
I get the identity constraint not declared warning in <keyref>s.
Can u pls check wt hv i done wrng?
Thanks in advance.

Could be a namespace problem: eg:
xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"

Would change that, and also use targetNamespace attribute.
