That would copy the rule from RFC 2616 "by value".

It's a prose rule; see RFC 5234 prose-val. It's used here to define the 
ABNF rule "by reference".

The reference form in theory is safer because there's only a single 
definition, so no conflicts are possible.

Best regards, Julian

PS: we use the prose-val style a lot in HTTPbis for referencing ABNF 
from other documents, so if there's a problem with that I'd like to 
learn ASAP about it :-)
