Lev: Thanks for your reply, just to make sure I understood your example so theoretically when encoding the open type with the length determinant the ending position of the encoding may or may not end up at an octet boundary although padding bits are inserted to make the content of the open type have a multiple of eight bits. Is this correct?

The only thing which is octet aligned in case od UNALIGNED PER is the number of bits in the field list of the type to be encoded. For example, if we normally encode some type in 3 bits, then, in case of an open type encoding, we shall construct a sequence of a. The encoding of the length determinant for "n", where n=1 b. 3 bits of meaningful content c. 5 bits of padding Without any octet alignment. -- Lev Walkin [EMAIL PROTECTED] --------------------------------------------------------------------- This transmission (including any attachments) may contain confidential information, privileged material (including material protected by the solicitor-client or other applicable privileges), or constitute non-public information.
