Re: Use of LWSP in ABNF -- consensus call

Since I composed this I saw additional opinions - one for doing  
nothing, and a couple that I interpreted as something stronger than a  
warning (e.g. "do not use in the future").  I still believe there to  
be rough consensus for a warning.  If anybody can suggest (or repost)  
very specific text this could help the authors.

Thanks,
Lisa
