6.2.5.4 FromPropertyDescriptor ( Desc ):
> The following algorithm assumes that Desc is a fully populated Property Descriptor,
> such as that returned from [[GetOwnProperty]] (see 9.1.5).
This is incorrect, partially populated Property Descriptors are valid. For example when `Object.defineProperty()` is called on an Exotic Proxy Object, 9.3.6 [[DefineOwnProperty]] will be called which in turn calls 6.2.5.4 FromPropertyDescriptor.

Left over text from the ES5 spec, but the algorithm no longer has that dependency.
