Re: Color Test: A formal proposal

Just FYI

Technically — we don’t have any such things as “formal tests”  except for TECHNIQUES.  


This can’t be a formal test unless the SC says that you must do exactly this - or rather  the SC must say  “  Content passes the following test"

you put it forward as an informal test — but the SC is the only criterion for passing the SC.  (that is what its name means—  success criterion. 

The WG COULD propose the test as a ‘sufficient’ test of the SC.   That is — if you pass, you pass.  
But you cannot say that if you fail you fail unless the SC says this specifically.
