Re: [Slim] Proposed 5.4 text

Hi Keith,

The document uses the terms "sign language tag" 
and "non-sign language tag", both terms applying 
to language tags.  Neither term is used in the 
absence of a tag.  The two terms are defined in 
Section 5.4.  I do not see why use of the terms 
is unclear or harmful, much less "entirely 
meaningless."  Along these lines, I don't see how 
the use of the "non-" prefix elsewhere is 
confusing or unclear; this is a very common 
prefix to use in Internet Drafts and RFCs.

-------------- Randomly selected tag: ---------------
[Some] billionaires [are] coming together under the leadership of Warren
Buffet and Bill Gates to donate their fortunes to worthy causes.... But
the billionaires with the strongest sense of class solidarity have an-
other plan for their disposable income: activating their lobbyists in
Washington, building grassroots movements to march on their behalf,
and using their media properties to run experiments on human credulity.
