Would anybody please confirm whether followings are correct?

1. Immediate packet assignment
New 2G RRC message, Immediate packet assignment, is introduced at sub-clause 9.1.18a in TS44.018 V10.4.0 (2011-09). But message type for this message is not defined in sub-clause 10.4 of this TS. Also, no CRs by GP-51 which are listed at the end of this TS does not include about this message. Is this message wrongly introduced in TS44.018 V10.4.0?

2. Implicit Reject CS/PS bits in IA Rest Octets
Implicit Reject CS/PS bits are added in IA Rest Octets (sub-clause 10.5.2.16)as follows. But is this correct?

<IA Rest Octets> ::=
{ LL < Compressed_Inter_RAT_HO_INFO_IND >
| LH
{ 00 < EGPRS Packet Uplink Assignment >
| 01 < Multiple Blocks Packet Downlink Assignment >
| 1 -- reserved for future use (however the value 7C for the first octet shall not be used)
}
| HL < Length of frequency parameters : bit string (6) >
< Frequency Parameters, before time >
< Compressed_Inter_RAT_HO_INFO_IND >
| HH { 00 < Packet Uplink Assignment >
| 01 < Packet Downlink Assignment >
| 1 < Second Part Packet Assignment >
}
{ null | L -- Receiver compatible with earlier release
| H -- Additions in Release 10
< Implicit Reject CS : bit >
< Implicit Reject PS : bit >
}
}
<spare padding>;

This means Implicit Reject CS/PS bits can be available only when first 2 bits is 'HH'. If Implicit Reject CS/PS bits should be available for other case too, CSN.1 should be like as follows.

<IA Rest Octets> ::=
{ LL < Compressed_Inter_RAT_HO_INFO_IND >
| LH
{ 00 < EGPRS Packet Uplink Assignment >
| 01 < Multiple Blocks Packet Downlink Assignment >
| 1 -- reserved for future use (however the value 7C for the first octet shall not be used)
}
| HL < Length of frequency parameters : bit string (6) >
< Frequency Parameters, before time >
< Compressed_Inter_RAT_HO_INFO_IND >
| HH { 00 < Packet Uplink Assignment >
| 01 < Packet Downlink Assignment >
| 1 < Second Part Packet Assignment >
}
}
{ null | L -- Receiver compatible with earlier release
| H -- Additions in Release 10
< Implicit Reject CS : bit >
< Implicit Reject PS : bit >
}
<spare padding>;
