				From our tool vendors' discussion, I think there was consensus that the normal case is padding to the right. That would be consistent with the result of tciEncodeValue which delivers a TriMessage which contains a left-aligned byte-array and the the bit-length.<br />
<br />
Thus, it would make sense to also expose the bit-length information to the TTCN-3 layer via an additional out parameter. If someone wants to turn the left-alignment to right-alignment, all they need to do is rotate the value by length-minus-bit-length to the right.<br />
