[Corona] Adding a sub-place to a place

[Ryan Grimm]

No, I don't believe that this is a use case that MarkLogic currently supports, and hence Corona can't either :). To support such an operation, MarkLogic fields (and/or element word queries) would need to support XPaths.

Sub-places in Corona can be thought of as more of an object inheritance model than a document structure model. Including place "A" inside place "B" simply tells place "B" to include all of the configuration from place "A". So if place "A" was configured to included elements "foo" and "bar", then place "B" is configured to include the element "baz" along with place "A", the result will be that place "B" includes elements "foo", "bar" and "baz".

Does that clear things up or muddy the water?
