 :star2: ECMA-402 spec must provide a deterministic order for the contents of all containers. This order should be lexicographic except in cases wherein there is a clearly preferable semantic ordering. :star2:
 
-For example, an array holding days of the week should store those days in the order `["monday", "tuesday", "wednesday", ...]` instead of `["friday", "monday", "saturday", "sunday", ...]`

+2. All properties (given in lexicographical order) that can be set by extension keys and that are guaranteed to exist
+3. Properties (in lexicographical order) that are not set by extension keys and that are guaranteed to exist 4. All properties (in lexicographical order) that exist conditionally. :star2:
