I'm not sure the <dl> should be here. Is it in the other snippets?

In encode_utils.h it has, and from the source c4cc963#diff-8ca48860d1bd768774f38f0f522ba91ef7dbb887e660917c74b7088da850752aL604 where I brought this from, it had it too.

Okay. When this PR is further along we can build the docs and check what it looks like. I'll leave this conversation open to remind us.
