Schema Versioning - A stylesheet to implement backward
Suppose an XML Schema issued to our business partners is updated with new elements but we want to continue to accept XML that conforms to old schema. Provided that the elements from the old schema are a subset of the elements in the new schema this can be done with a transformation. I have written a stylesheet that takes an XML Schema call it old-schema as a parameter and given xml conformant to the new schema derives an xml instance that is conformant to old schema . I believe this to be a generically useful solution and would like some suggestions as to where to publish the code - I was thinking EXSLT but have never done anything like this before and am not sure it is the right forum.
