What puzzles me is that the XML structure (nesting) doesn't follows the 
lexical Ada source structure. Example from avatox.adb --> avatox.adb.xml:

<A_CLAUSE ... startLine="29" endLine="29" startCol="1" endCol="29">
   <A_WITH_CLAUSE ... startLine="29" endLine="29" startCol="1" endCol="29"/>
   <AN_EXPRESSION ... startLine="29" endLine="29" startCol="6" endCol="28">
     <A_SELECTED_COMPONENT ... startLine="29" endLine="29" startCol="6" 
endCol="28"/>
     <AN_EXPRESSION ... startLine="29" endLine="29" startCol="6" endCol="19">
       ....

You can see that <A_WITH_CLAUSE> from (29,1) to (29,29) lexically contains 
<AN_EXPRESSION> from (29,6) to (29,28). But the latest is not nested inside 
the former. Instead, it appears as a sibling of it.

The same for <A_SELECTED_COMPONENT> from (29,6) to (29,28) and 
<AN_EXPRESSION> from (29,6) to (29,19).

Is that the intended behaviour?
