Re: [rfc-i] Poll: RFCs with page numbers (pretty please) ?

[Paul Kyzivat <[e-mail]>]

If paragraph numbering were added to the txt format, and didn't break 
the diff tools) IMO it would solve the problem of making references into 
long sections.

Note that there is already sometimes a problem in going from the side by 
side diff format to the corresponding place in the full document, 
regardless of format. Paragraph numbers would help solve that too.

	Thanks,
