Wrong packing of attributes?

If you are working on a VPWS service flow in an Alvarion 4-Motion base
station you will have to do some steps to fix the NAS.
1. Update to the latest version for 2.2
2. Define the R3 attributes in a separate dictionary.
3. Update the main dictionary.wimax to make sure all of the Alvarion
WiMAX- attributes are added to that dictionary
4. Let me know any success as I have yet to get the NAS to properly
accept the service flow.
Let me know if you need any dictionary files for that NAS.

I'm on a bit of a limb here, but I think I might have found a bug. Far from
sure though, so please don't kill me if I'm wrong.

The problem here though, is that the following attributes:
WiMAX-QoS-Id = 1
01 03 01
WiMAX-Schedule-Type = Best-Effort
04 03 02
WiMAX-Traffic-Priority = 1
05 03 01
WiMAX-Maximum-Sustained-Traffic-Rate = 2000000
Should really be packed into a WiMAX-QoS-Descriptor,as far as I can see?
Cut'n'paste from Dictionary:
ATTRIBUTE WiMAX-QoS-Descriptor 29 tlv
ATTRIBUTE WiMAX-QoS-Id 29.1 byte
ATTRIBUTE WiMAX-Global-Service-Class-Name 29.2 string # 6
octets
ATTRIBUTE WiMAX-Service-Class-Name 29.3 string
ATTRIBUTE WiMAX-Schedule-Type 29.4 byte
ATTRIBUTE WiMAX-Traffic-Priority 29.5 byte
ATTRIBUTE WiMAX-Maximum-Sustained-Traffic-Rate 29.6 integer
ATTRIBUTE WiMAX-Minimum-Reserved-Traffic-Rate 29.7 integer
ATTRIBUTE WiMAX-Maximum-Traffic-Burst 29.8 integer
ATTRIBUTE WiMAX-Tolerated-Jitter 29.9 integer
ATTRIBUTE WiMAX-Maximum-Latency 29.10 integer
ATTRIBUTE WiMAX-Reduced-Resources-Code 29.11 byte
ATTRIBUTE WiMAX-Media-Flow-Type 29.12 byte
ATTRIBUTE WiMAX-Unsolicited-Grant-Interval 29.13 short
ATTRIBUTE WiMAX-SDU-Size 29.14 short
ATTRIBUTE WiMAX-Unsolicited-Polling-Interval 29.15 short
ATTRIBUTE WiMAX-Media-Flow-Description-SDP 29.16 string
And should most definately *not* be included in the
WiMAX-Packet-Flow-Descriptor.
Am I messing up something here, or could there be a bug in the encoder?
