Dear Ananda:
Thank you for your comment. Your request is in the general category of
co-occurrence constraints or
co-constraints. There is a requirement for Schema 1.1 to support some
form of co-constraints.
All the best, Ashok

Hi XML Schema Team,
In EDI-X12, there is a concept called conditional requirements.
For instance,
<complexType name="AccountInformation">
contains the following elements
1. AccountNumber
2. Name
3. IdentificationCodeQualifier
4. IdentificationCode
5. AccountNumberQualifier
6. AccountNumber
7. Description
8. PaymentMethodCode
9. BenefitStatusCode
</complexType>
Here I need the following conditional requirements
(1) if 05 is present 06 must be as well.
(2) if 07 is present 05 must be as well.
(3) if any one of 03, 05 is present then all must be present.
It could be useful if you provide a straight forward facility to
specify conditional requirements in XML Schema V1.1
Regards,
Arasu.
