Duplicated Error Code 459

Hello all,

H.248.26 specifies error code #459:
/7.5.1 Invalid Combination of Metering Detection Events
Error Code #: 459
Name: Invalid Combination of Metering Detection Events
Definition: The command was disregarded because the Events Descriptor 
contained more
than one metering detection event.
Error Text in the error Descriptor: --
Comment: –/

However H.248.18 (and the IANA registration page) also specifies error 
code #459 as:
/5.6 Error Codes
This package defines a new error code:
#: 459 Name: Unsupported or Unknown Profile
Definition:
The Profile Name is not supported by the receiver. The command related 
to the unknown
profile is disregarded.
Package: Profile Package prp, 0x0050
Reference: H.248.18
Error Text in the error Descriptor:
The Profile Name is included in the error text in the error descriptor. 
String Length 1 –
67 characters – 64 for name, 1 for "/" and 2 for version.
Comment: −/

This leads to a duplication of error codes numbers. One of the numbers 
needs to be changed. If we take the precedence of the Recommendations 
then H.248.18 should remain and H.248.26 should be changed. However my 
feeling is that H.248.26 currently has a wider usage. I propose the 
usage of the error code number 461. Any preferences on whether H.248.18 
or H.248.26 should be changed?

Any thoughts?
