Yeah, I had that in mind in the beggining, but it has never been 
implemented since I didn't stumble upon a proper syntax yet...

Hmmm of course that's a possibility, but I don't think we should mix 
formsess syntax and smarty syntax, what do you think ? Of course it 
would be totally useless to rewrite loops code and all that stuff for 
formsess itself but I'm not sure it is the way to go... I have to think 
about it.

Theorically, if you do something like $smarty.formsess.formname.errors 
(or any similar syntax), it can be done, since formsess uses a kind of 
singleton pattern. Not properly implemented yet, though _ has to be done 
for 2.0.0 _ but it should work. We would have to write a wrapper with 
our own syntax though... since calling that from outside a form would 
require to create a formsess instance if it was not created before, the 
way it's done in the fs:form tag.
