Lead. It has an engaging lead that introduces the subject and defines the scope and inclusion criteria.
(a) It comprehensively covers the defined scope, providing at least all of the major items and, where practical, a complete set of items; where appropriate, it has annotations that provide useful and appropriate information about the items.
(b) In length and/or topic, it meets all of the requirements for stand-alone lists; does not violate the content-forking guideline, does not largely duplicate material from another article, and could not reasonably be included as part of a related article.
