It probably won't help you much though as this is work in progress and I doubt any tools support it. You can find more about Schematron at: http://www.schematron.com/. Although you can write XSD schemas that contain Schematron constraints I'm not sure how many mainstream parsing tools support this. I have only limited experience of ASN.1. To my knowledge ASN.1 does not support this type of constraint, but I could easily be wrong. It may just be easier to make this an application level check!
