RE: IDREFS and key()
In 2.0 you don't need the key() function to do this, you can do it using the idref() function. If you want to do it using key(), your key definition would work (the value would be indexed on each string appearing in the @references attribute) provided you use a schema-aware processor and @references has a list type. If you want to do it using a 2.0 basic processor, you can specify use="tokenize(@references, '\s')". If you want to do it using 1.0, you're a masochist...
