Um, beg to differ.  Lax processing is recursive, so the non-beta
children of alpha will be laxly validated as well, unto the n-th

The relevant quote from the REC is:

  "[A]n element information item's schema validity may be laxly
  assessed if [it was accepted by a 'lax' wildcard and no top-level
  declaration for it was found] by validating with respect to the
  ur-type definition"
