I think it's exactly that, a NESTED which doesn't nest.
I have few other problems to solve first, sorry for not getting back.
Are there any tests with nested in watchdog ? I could work on one
and try to reproduce ( or find what's going wrong ).
BTW, I noticed that the .tlds and are parsed on every page
compilation. Can I add an option to allow bad developers to disable
at least validation ? ( I know a good developer will validate the xml
as many times as possible, to be sure :-). I also have a small patch that
caches the trees ( well, if I had more time I would get rid of
the whole DOM->tree duplication and use dom directly ).
