Well, then let's look at data types that have partial orders on their value space (duration and date/time types), let's look at allowing pattern facets to restrict the value space based on the lexical representation on types that have more than one lexical representation for the same value. That is only the tip of the iceberg. On the last point: restrictions should be on the value space, if you have such a beast. However, XSD has these things now and I have to blame myself for not screaming louder. To get the benefit of interoperability, you either swallow the pill and work on mitigating its impact (see XQueries duration types, or best practices papers that say" Don't use pattern facets on non-string types) and work on improvements, or you go and start from scratch. Some people cannot wait to get the latter done and made the trade-off that the first approach is better short and midterm and work towards making it improve for the longterm.
