John,

Martin is totally right. You can't 'de-comment' something by overloading 
and setting it to true or false will still make ant failing since the 
except="" attribute will work based on the existance of that property, 
not its value.

But even more important, watch your tone! Martin was trying to help and 
even if he was wrong, he still deserves your respect.
