Using W3C Schema 1.0 you cannot express that as a constraint. >Something like : ><xs:simpleType name="a" value = any string OR another element b of >type string> Using the ISO/IEC 19757-3 Schematron assertion-based constraint language you can express your desired constraint, but it is run separately from W3C Schema. Off hand I'm not sure if the future W3C Schema 1.1 can help in this regard ... I suspect that it can since it supports co-occurrence constraints, but I don't know if there are limits. I hope this helps. . . . . . . . . . . . . .
