Key 'Yes' not found for keyref constraint ...

["Samuel B. Quiring" <sb...@Cayuse.com>]

I'm getting a validation error on the XML generated for the schema snippet below:

validationError: error: cvc-identity-constraint.4.3: Key 'Yes' not found for keyref constraint 'TotalFundForAttachedKeyPersonsExistKeyRef2@http://apply.grants.gov/forms/RR_Budget-V1.0'

Does anyone have any idea what this means?  I've been trying to figure this out for a couple of hours.  Here is the relevant XML that is generated:

--------------------------------------------------------------------------------

          <rr:FundsRequested>40</rr:FundsRequested>
          <rr:BaseSalary>90</rr:BaseSalary>
      </rr:Compensation>
  </rr:KeyPerson>
  <rr:TotalFundForAttachedKeyPersons rr:TotalFundForAttachedKeyPersonsExist="Yes">101</rr:TotalFundForAttachedKeyPersons>
  <rr:TotalFundForKeyPersons>51</rr:TotalFundForKeyPersons>
</rr:KeyPersons>
