There are algorithms that can validate <all> nested within <all>, or whatever (see http://www.thaiopensource.com/relaxng/jing.html for example), but it's just that W3C XML Schema decided not to allow them for some reason. So your options are either - stick to W3C XML Schema and make a compromise by using (a|b)* rather than (ab|ba)*. - or switch to another schema language that allows you to express what you want. regards, ---------------------- K.Kawaguchi E-Mail: kohsukekawaguchi@yahoo.com
