DocType Setting Effect

 Folks,

   I've searched the archives and found some emails that spoke to this,
but they're about 4-5 years old, so I'd like to know if the situation has
changed since then.

   When you set the doctype value to strict, does this have any effect
beyond controlling what DOCTYPE declaration tidy puts in its output?
Setting the doctype to strict does not seem to cause tidy to throw any
errors when encountering invalid XHTML as opposed to warnings.  I'm
not sure if it just doesn't do this, or if I'm just doing the wrong thing.

thanks,
Jim
