A field map describing the state of a resource. Each field holds a value set: a single
scalar value, a Dictionary, or an array of scalars. A property carrying no value is
absent from the map rather than present with an empty marker; undefined is admitted as the absent marker for a
field elided at construction time (for example, a conditionally included property) and is equivalent to omission.
Note
A vacuous nested Resource, such as {} or { "address": {} }, carries no state and MUST
be ignored by processors: dropped when it appears as an element of a Values array, or treated as if the
owning field were omitted from the enclosing resource otherwise.
