Well, it's a little delicate here. Even if we support multi-byte tag one day,
this constructor will still only be used to create a single-byte tag
`DerValue`, and it's illegal for a single byte tag to end with 0x1f. So the
words above is to remind people that they cannot create a tag number 31
`DerValue` just because it seems it still fits into the 5 bits. Precisely, the
words should be "this constructor only supports tag number between 0 and 30",
but... I'll choose your words.
