H.450.3 call forwarding supplementary services

Hi In H.450.3, call forwarding supplementary services, the response to interrogateDiversionQ.Invoke APDU is defined as follows

IntResultList ::= SET SIZE (0..29) OF IntResult IntResult ::= SEQUENCE { servedUserNr EndpointAddress, basicService BasicService, procedure Procedure, divertedToAddress EndpointAddress, remoteEnabled BOOLEAN DEFAULT FALSE, extension CHOICE {extensionSeq ExtensionSeq, nonStandardData NonStandardParameter } OPTIONAL,

?

}

I would like to know, why the result has been kept a list of maximum 29 nodes. As far as my understanding goes, a list of 3 nodes would suffice, one node for each service type (CFU/CFB/CFNR).

Ane help would be appreciated.

Thanks
