How's the contradictory -- note this is in contrast to "don't validate" on the one hand (skip) and "validate where you can, error if you can't" (strict). > Reading the spec, I find it hard to see how your quote from is said > to apply specifically to wildcard declarations where processContents > is lax. I also note the use of the word "may" in the quoted excerpt. The interpretation of the declarative language of the spec., which speaks about what is and isn't valid, in terms of control flow, is tricky at this point, I agree -- it requires a sort of backward-chaining through the prose, which then has to be "run" in a forward direction by an actual validator. With hindsight (which, as the saying goes, is often 20-20), we should have found a different way to express all this. The use of the word 'may' has to be understood in the context of that backward-chaining -- it ends up with full 'required to' force when takin in conjunction with other aspects of the definition of validation, expressed elsewhere in the REC. Having said that, the language isn't as helpful here as it should be, I agree. I can't quickly check, but are you saying the the MS schema validator _doesn't_ recurse after matching a lax wildcard? ht -- Henry S.
