When a binding document is added, we store all element="" selectors in a <tt>RuleHash</tt>, templatized as <tt>nsSelectorHash</tt>.

Notifications happen by modifying <tt>nsNodeUtils</tt> such that the XBL2 code is notified after the root of any subtree. This avoids having to have the XBL2 code register a <tt>nsIMutationObserver</tt> for every orphaned subtree. | Notifications happen by modifying <tt>nsNodeUtils</tt> such that the XBL2 code is notified after the root of any subtree.
