> @annevk what whitespace are you talking about here? There's no OWS in [the spec](https://httpwg.org/specs/rfc9110.html#rule.ranges-specifier).
@mnot I thought the same thing originally, but [section 2.1](https://httpwg.org/specs/rfc9110.html#abnf.extension) states:
> It also uses a list extension, defined in [Section 5.6.1](https://httpwg.org/specs/rfc9110.html#abnf.extension), that allows for compact definition of comma-separated lists using a "#" operator...
The relevant text from [Section 5.6.1](https://httpwg.org/specs/rfc9110.html#rfc.section.5.6.1) states:
> A construct "#" is defined, similar to "*", for defining comma-delimited lists of elements. The full form is "<n>#<m>element" indicating at least <n> and at most <m> elements, each separated by a single comma (",") and optional whitespace ([OWS](https://httpwg.org/specs/rfc9110.html#whitespace), defined in [Section 5.6.3](https://httpwg.org/specs/rfc9110.html#whitespace)).
So [range-set](https://httpwg.org/specs/rfc9110.html#rule.ranges-specifier) could have optional whitespace due to the use of the list extension.
Please let me know if I've missed something!
