On more careful examination, however, I see that we fixed this problem. Conditional type assignment only has access to the values of "inheritable attributes" that have the same validation context as the element being validated, so in effect attributes outside the validation root don't affect the outcome, just as element names outside the validation root don't. Sorry for this excursion up the garden path. Michael Kay Saxonica
