Re: Caution about Style Sheets

Actually, the question started as to why 6.1 was needed.    Someone could 
use the infamous font tag to change style or font.  The ban on the font tag 
is only priority 2.  Whereas the ban on using color alone is, 
appropriately, priority 1.  So something is needed to make the ban on using 
font or style alone a priority 1, and generalizing the color alone 
checkpoint seems like a nice place to squeeze that in.
