1/// Slash namespace — `http://purl.org/rss/1.0/modules/slash/`
2/// WFW (Well-Formed Web) namespace — `http://wellformedweb.org/CommentAPI/`

4/// These namespaces are commonly used together in `WordPress`, `Blogger`, and
5/// `Movable Type` feeds to expose comment metadata.
6///
7/// - `slash:comments` — integer count of comments on an entry
8/// - `wfw:commentRss` — URL of the entry's comment RSS feed
