Custom validation

[Kar, Swayambhuba]

My requirement is to validate a XSD schema definition against a profile of W3C schema. i.e there are restrictions around if certain elements in W3C schema definition language can appear in the schema definition.   For example, I don’t want to allow xs:redfine in the schema definition and I should be able to detect that while the schema is being parsed.   Any pointers on how to go about doing this?   - Swayam Hewlett Packard,14475 N.E. 24th Street,Bellevue, Washington,United States,98007,425-401-6029
