I agree that we should be careful to speak of registering "subtags" and 
not "tags," both in registration forms and in general discussion.  The 
only thing we do with tags is reclassify them from grandfathered to 

I have no idea what Suppress-Script has to do with the subtag 'zxx', 
which means "No linguistic content" or "[Language] Not applicable." 
This subtag could refer to non-linguistic content in a writing system, 
such as a Snellen eye chart or "lorem ipsum" gobbledygook.  Such content 
could just as easily exist in Cyrillic, Arabic, or some other script as 
in Latin.  Then there is all the 'zxx' content that is in no writing 
system at all, such as the Mona Lisa or Beethoven's Eroica Symphony.  In 
neither case would it make any sense to assume a particular script, 
which is what Suppress-Script is all about.
