Then you are looking for all li elements whose closest ancestor ul
element is equal to the element with ID 'a'. That's trivial in XPath,

  //li[ ancestor::ul[1] = id('a') ]

You cannot create a equivalent CSS Selector without the notion of
"closest ancestor" or "immediate descendants" if you begin the ex-
pression with the ul element. What you can do, of course, is

  ul#a li    { ... }
  ul#a ul li { ... }

which would cover most, if not all, use cases, as far as style
sheet authoring is concerned.
