Question: resource-id or requested-number about OF-CONFIG 1.2 spec OpenFlow Port

[JackLIN-F]

Hi,
Who is know about OF-CONFIG 1.2 spec OpenFlow Port?
I cannot found requested-number leaf on OF-CONFIG 1.2 spec.
I found resource-id leaf on OF-CONFIG 1.2 spec.

In of-config.yang file:
leaf requested-number {
type uint64 {
range "1..65279";
}
description
"This is the requested OpenFlow Port number for this interface. The switch
is expected to try and use the value of this lead as the port number for
the interface. If the switch is unable to use the requested value or if
this leaf is not present, it will choose a free port to use.";
