I find that no schemas examine constraints specified
in RFC 4287 (The Atom Syndication Format),
RFC 4685 (Atom Threading Extensions), "Feed Paging and Archiving",
and Open Search, all together.
I gave a lecture of schema customization at Tsukuba University and
asked the students to try. On the basis of their result, I created a
schema for the combination of the above specifications. Furthermore,
other extensions can be easily added to this schema.
The schemas are available at:
http://www.asahi-net.or.jp/~eb2m-mrt/atom/schemaForAtomExtensions.zip
The schema "atomRev.rnc" is a rewrite of the schema in RFC 4287. It is
created by Mr. Fujisaki at Tsukuba University, and is slightly modified
by me.
