Thanks for your clarification.
There is actually another point wrt referrals:
The REPORT REFERRALS command allows you to specify up to 8 bytes of
allocation length.
Yet the parameter data returned allow you to specify only up to _2_
bytes for returned data (namely byte 2 & 3), with the top 2 bytes
remaining reserved.
Shouldn't those two numbers be aligned?
I would actually prefer to lower the size for the allocation length
to 4 bytes and raise the size for the parameter size to 4 bytes.
Otherwise the standard would impose quite a limitation on
the number of possible user segments, making it unusable for some
application scenarios.
Thanks for your time.
Cheers,
Hannes
