NAD; what the standard says is that this is "undefined", not "unspecified".

Jonathan: This breaks all known implementations of parallel algorithms, since they use custom execution policies.
Alisdair to check with SG1 to see if that's what they meant.
A user specialization of any is_execution_policy should produce an ill-formed program, not merely one whose behavior is unspecified. See also the related comment re [meta.type.synop] (20.15.2). (US 10)
Proposed change: Reword the paragraph as follows:
See also LWG 2871.Unless otherwise specified, a program that adds specializations for is_execution_policy is ill-formed; no diagnostic required.
