Hi Pieter,
> The *human-readable part*, which is intended to convey the type of data,
or anything else that is relevant to the reader. This part MUST contain 1
to 83 US-ASCII characters, with each character having a value in the range
[33-126]. HRP validity may be further restricted by specific applications.
You should also add to this section that the HRP should be lowercase.
Since Bech32 forbids mixed-case and otherwise converts everything to
lowercase, it is good to warn upfront against using uppercase in the HRP.
I know the BIP is marked as final, but this wouldn't be a normative change.
