I believe "</" is only valid in script and style elements according to 
SGML rules when it is the end-tag for the elements, and therefore, must 
be of the form </script>, </style> or the SHORTTAG NET form </>. 
However, since SHORTTAG is not supported, only </script> and </style> 
should be allowed.

Agreed.  That is how HTML 4 validators currently work.
