Marc and I disagree on this one. My approach in asis2xml is to have

    <context_clauses>
      <with_clause>
        <selected_component>
          <selected_component>
            <identifier>Ada</identifier>
            <identifier>Characters</identifier>
          </selected_component>
          <identifier>Handling</identifier>
        </selected_component>
      </with_clause>

but it would be just as sensible to have

    <clause kind="with_clause">

The XPATH expressions aren't that different:

   A_CLAUSE[A_WITH_CLAUSE]
   with_clause
   clause[@kind='with_clause']

It depends what would be most useful. As an example of where user
input would be good, what about that <selected_component> structure,
which does follow the lexical structure of the language, but imagine
the query to find all withs of Ada.Characters.Handling!
