== Why is this an issue?

Certain prefixes are widely recognized and expected to correspond to specific namespaces. For instance, most users will expect "xs" to correspond to "http://www.w3.org/2001/XMLSchema". If you subvert that expected correspondence, you run the risk of severely confusing the users of your XSD.
