Review "@container": { "@list" }

[lanthaler]

There was a short discussion as part of discussing issue #68 how "@container": { "@list" } is supposed to work and whether @set (see also issue #44) is needed.

The main issues are:

• if we do not add support for "@container": { "@set" }, why do we need @container at all then?
• if "@container": { "@set" } is expected to always expand/compact to an array, shouldn't @list do the same (currently it doesn't)?
• would something like @ordered and @unordered be better instead? (they could be added to @type eliminating the need for @container)

I close this issue as all of this was discussed in recent telecons.
