<https://greenbytes.de/tech/webdav/draft-ietf-httpbis-header-structure-18.html#rfc.section.3.1>:
3.1. Lists
Lists are arrays of zero or more members, each of which can be an Item (Section 3.3) or an Inner List (Section 3.1.1), both of which can be Parameterized (Section 3.1.2).
The ABNF for Lists in HTTP fields is:
sh-list = list-member *( *SP "," *SP list-member )
list-member = sh-item / inner-list
So the prose says zero elements are allowed, but the ABNF actually
requires one element.
One of these is incorrect...
You saw
An empty List is denoted by not serializing the field at all.
right?
That's about serialization.
4.2.1 seems to parse an empty string into an empty list.
AFAICT, that's in conflict with the ABNF.
Best regards, Julian
