Comment:
Section: "Parsing an event stream"

It looks like their is a mistake in this ABNF description, "end-of-line" is
repeated: 

stream	      = [ bom ] *event
event	      = *( comment / field ) end-of-line
comment       = colon *any-char end-of-line
field	      = 1*name-char [ colon [ space ] *any-char ] end-of-line
end-of-line   = ( cr lf / cr / lf / eof )
eof	      = < matches repeatedly at the end of the stream >

If "end-of-line" is set at the end of the "event" description, it shouldn't be
repeated at the end of the "comment" and "field" descriptions.

"eof" could be proposed as an alternative of "end-of-line" instead of being
part of the "end-of-line" description

Update proposal:

stream	      = [ bom ] *event
event	      = *( comment / field ) (end-of-line / eof)
comment       = colon *any-char
field	      = 1*name-char [ colon [ space ] *any-char ]
end-of-line   = ( cr lf / cr / lf )
eof	      = < matches repeatedly at the end of the stream >

Status: Rejected
Change Description: no spec change
Rationale: It's repeated because <event>s are separated from each other by a blank line. Your proposed BNF puts all the comments and fields on one line, which is unparseable.
