   * Attribute not equal selector
   * Positional selectors (:first; :eq(n); :odd; etc.)
   * Type selectors (:input; :checkbox; :button; etc.)
   * State-based selectors (:animated; :visible; :hidden; etc.)
   * :has(selector)

   * Reliable functionality on XML fragments
   * Requiring all parts of a selector to match elements under context
   *   (e.g., $div.find("div > *") now matches children of $div)
   * Matching against non-elements
   * Reliable sorting of disconnected nodes
   * querySelectorAll bug fixes (e.g., unreliable :focus on WebKit)

  /*
  	Implementation Summary
  
  	1. Enforce API surface and semantic compatibility with 1.9.x branch
  	2. Improve the module's maintainability by reducing the storage
  		paths to a single mechanism.
  	3. Use the same single mechanism to support "private" and "user" data.
  	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
