APA has a variety of standard terms that should be added to enable better use of apa.csl across locales. MLA has a similar set of terms, but I'm less familiar with that style.

In addition to terms for new types of creators and a general term for each item type (e.g., patent, map, song [which might be localized in English as "Audio recording"]), I think the following should be added:

1. album
2. advance-online-publication
   • This is distinct from in-press or forthcoming
3. personal-communication
4. article
   • for "Article No. e012345"
5. preprint
6. working-paper
7. original-work-published
8. on
   • for a track on an album (rather than in an album)
9. review-of
10. film
11. video
12. television-series
13. radio-broadcast
14. podcast
15. special-issue
16. special-section

Perhaps also

1. number
   • currently term="issue" (localized in English as "No.") is used, which works, so perhaps this one is unnecessary

Adding these would go a long way toward making APA transportable across locales, and it could even eliminate some requirement of users to manually enter genre into their data (e.g., a client could automatically add term:podcast to a Podcast boadcast items). (The term:term behavior is a new propsoal`.)
