Message signatures, structured fields and ABNF

Dear all,

after reading the HTTP Style guide
I was trying to refactor RateLimit
to remove ABNF and I am finding the document less readable than before.

Looking at
I think that removing ABNF from there is even more complicated.

Which is a suitable replacement for ABNF to be used in cases such as
Message Signatures?
While Structured Fields is capable of disassembling the structure of  a field,
it can't formally describe the specific content/format of a string.

Kind regards,
