  Ordinary descriptor validation if [[Value]] is absent.

  ArraySetLength ( A, Desc )

  1. If Desc.[[Value]] is absent, then
    a. Return OrdinaryDefineOwnProperty(A, "length", Desc).

  OrdinaryDefineOwnProperty ( O, P, Desc )

  [...]
  3. Return ValidateAndApplyPropertyDescriptor(O, P, extensible, Desc, current).

  ValidateAndApplyPropertyDescriptor ( O, P, extensible, Desc, current )

  [...]
  4. If current.[[Configurable]] is false, then
    a. If Desc.[[Configurable]] is present and its value is true, return false.
    b. If Desc.[[Enumerable]] is present and
      ! SameValue(Desc.[[Enumerable]], current.[[Enumerable]]) is false, return false.
  [...]
  6. Else if ! SameValue(! IsDataDescriptor(current), ! IsDataDescriptor(Desc)) is false, then
    a. If current.[[Configurable]] is false, return false.
  [...]
  7. Else if IsDataDescriptor(current) and IsDataDescriptor(Desc) are both true, then
    a. If current.[[Configurable]] is false and current.[[Writable]] is false, then
      i. If Desc.[[Writable]] is present and Desc.[[Writable]] is true, return false.
