No. You'd either have to go outside XML Schema for that, or change the way you represent email addresses, so that the com/org/gov etc. parts are held in a separate element or attribute. > 3) I was awkwardly using ^, what I meant was: "[^a]@[^b]\.com" but > anyway as you acutely highlighted: no antipattern facet nor no but. > Do you know if w3c is thinking about antipattern or but?

It does sound as if something like an anti-pattern facet would be useful. The W3C is still soliciting suggestions for XML Schema 1.1, so perhaps you should write to www-xml-schema-comments@w3.org with the suggestion and your use case.
