-// Conversions for IDBKey.

-// Per http://www.w3.org/TR/IndexedDB/#key-construct
-//
-// "A value is said to be a valid key if it is one of the following types: Array
-// JavaScript objects [ECMA-262], DOMString [WEBIDL], Date [ECMA-262] or float
-// [WEBIDL]. However Arrays are only valid keys if every item in the array is
-// defined and is a valid key (i.e. sparse arrays can not be valid keys) and if
-// the Array doesn't directly or indirectly contain itself. Any non-numeric
-// properties are ignored, and thus does not affect whether the Array is a valid
-// key. Additionally, if the value is of type float, it is only a valid key if
-// it is not NaN, and if the value is of type Date it is only a valid key if its
-// [[PrimitiveValue]] internal property, as defined by [ECMA-262], is not NaN."
-
-// What is required is to ensure that an Lists in the key are actually
-// JavaScript arrays, and any Dates are JavaScript Dates.
