Hi,

The W3C Web Performance WG would like to register the
"Timing-Allow-Origin" HTTP response header field, defined in the
Resource Timing specification, as a provisional registry. Please let us
know if there is any further question.

------------
Header field name: Timing-Allow-Origin
Applicable protocol: http
Status: standard
Author/Change controller: W3C
Specification document: Resource Timing Level 1
<https://www.w3.org/TR/resource-timing-1/> Section 4.5.1

Thanks.
