Speaking for those that has in the past had to read and parse the hexdump of
PER encoded
PDUs:    Very few things, if any, are convenient when it comes to PDU.  :-)

While being a very compact encoding, convenience in parsing the data is not
one of the
features of asn.1/per.

(thank god h323 at least use aligner-per and not unaligned per)
