WARNING: $cap is not identical to the @PRE action cap( ). $cap will traverse down to the leafiest node it can find, in order to perform its check. The @PRE action only chains down if the [s] flag is present in the associated phrase element(s). Also, $cap is not stopped by a [base] attribute in a node.
