Why do we need to treat these differently? We want all of the schema files to be treated the same. If we need to group them to show the dependencies, then we should figure out how to do that (probably by generating some YAML file to iterate over rather than trying to do anything complex in Jekyll/Liquid). But for now, just showing all revisions for all four is correct (and ideally also showing the old */base ones since we should schema/$date and schema-base/$date that depend on them.

We want all of the schema files to be treated the same.

That would mean that base is before the newer date-stamped iterations because "the same" means "in descending lexicographical order". Moving base after the newer date-stamped iterations exceeds my Liquid skills - I've tried and failed.

@ralfhandl Oh I see, I had misunderstood this a bit. Let me think on it...
