        foo,bar,baz

  Descendants
    Use the slash operator to select properties within properties:

       foo/bar/baz

    will return the 'baz' property of the 'bar' property of the 'foo'
    property.

    Arrays are handled transparently: if 'foo' is an array, then the rule
    'bar/baz' will be applied to every entry in 'foo'.

  Sub-selection
    Use the parentheses to select specific properties from inside another:

        foo(bar,baz)

    selects the 'bar' and 'baz' properties from 'foo' (or from each element
    in 'foo').
