So getKey() might be a method of Dinamic interface.
And getValidator() also might becom a member of the Dinamic interface?

Hmm.. intresting thing.. looks like even the XSLT processor, if it get access to 
request parameters, cookies and http headers as it did for C1 becomes dinamic in
this sence and should return getKey()!! 

Tricky but I think this would be even beautifull!

(Or we could regturn getKey()== null if are not actually dinamic.)
