Current text: 'RSS feeds ... ... are RSS version 2.0, and ... Atom feeds are ... version 0.3.'
The Atom support onsite was updated from v0.3 to 1.0, a while back. There might be a couple of things that're still be ironed out in terms of 100% compliance. Either way, it's "pretty much" version 1.0, and is no longer version 0.3.
Further down, it reads: "Feeds include the subject (when present), the full text of the entry...". This is true for RSS feeds. A constructed title ('subject') will be auto-inserted for each entry in an Atom feed though, if the user didn't provide their own.
In an RSS feed, no user-provided entry title will just mean the title tag is omitted. No user-provided entry title in an Atom feed, on the other hand, means it's still included, and content inserted inside it:
<title>exampleusername @ 2005-12-19T00:00:00</title>. There was a suggestion that this auto-correction be removed, but it's there at the moment anyway. The rest of the sentence quoted above mentions feeds carry the full text of the entry... this should probably stay as it is the standard account behaviour.
I'm not sure of what wording to suggest. Perhaps something along the lines of...
"The Atom syndication format requires a title element for each entry. If the entry did not include a subject, the username or communityname and time of posting are inserted inside the title element. Example:
<title>exampleusername @ 2005-12-19T00:00:00</title> FAQ #151 "Why might a syndicated account not update correctly?". This was tweaked recently but making it more implicit that 'a UTF-8 feed is best, if you have the choice' might make things easier too.
E.g:
- * The feed must use a text encoding which LiveJournal recognizes.
+ * The feed must use a text encoding which LiveJournal recognizes, such as Unicode (UTF-8) encoding.
