[Serializer] Document the custom normalizer options

For instance, the format pattern included by #7063

I'm closing this old issue because it didn't gain any traction and also, because we usually don't document/explain all arguments/options of all methods in the docs. Thanks.

I'm going to reopen this because I think I was wrong. It's true that we don't document method arguments ... but this could be referring to something else. Sorry.

Thank you for this issue.
There has not been a lot of activity here for a while. Has this been resolved?

Hello? This issue is about to be closed if nobody replies.

[wouterj]

No,it hasn't. Recently, we've documented all encoder options, so I think it makes sense to add normalizer options as well.
