Yves,



Let me answer the easy question first:



At 08:52 AM 4/2/2007, you wrote:
2) I tried, of course, to test for the empty sequence as recursion 
terminator instead of testing for the token 'NONE'. Unfortunately, 
neither of the following test expressions worked, with 
$style_names_list initially set to ('b', 'i', 'u'):



$style_names_list = ()
$current_style_name = ''
$current_style_name = ()

The expression "empty($style_names_list)" will return true when 
$style_names_list is an empty sequence.



It's syntax sugar in XPath 2.0 (and quite sweet too).



Cheers,
Wendell
