I'd say that's realistic.  Most XML APIs present attributes in a bag,
such that it's easiest to find the ones you understand and ignore the

I'd say that ifUnknown needs three values:  "ignore", "fail", and
"continue", where the third means to process the children of this
element as if they were children of its parent (the way HTML browsers
work).   In the nature of things, these can only be advisory, of course.

I'm not sure what dependency means in this context.
