For my own purposes, I think of substitution groups as instituting a form of polymorphism, whereas xs:choice is a "dumb" switch statement. The former is quite useful if you expect to introduce new things into a vocabulary you want to treat in existing software without modification. The latter is for when you just want a switch. But that's just me. HTH. Best regards, David Ezell
