QoS is a mess. In MAP there is qos-Subscribed which is then extended
using ext-QoS-Subscribed, ext2-QoS-Subscribed, ext3-QoS-Subscribed
and maybe even ext4-QoS-Subscribed by now. The MAP ASN1 files defined
how these need to be "linearized". Instead of copying this I have
decided to include the two semantics with/without the Allocation/Retention
policy using the size of the data.
Currently the definitions of the message PURGE_MS_RES and
PURGE_MS_ERR are missing in the specification.
This patch adds those definitions.
