Bytes are in most significant to least significant order (increasing addresses on the tag). The bitstring is aligned at the most significant bit. Zero padding on the right (least significant).

Well actually representing bit arrays with raw binary bitstrings in the XML would be unwieldy and difficult to look at. So I elected to represent bit arrays as hexadecimal, with no spaces between. The problem you run into is that xs:hexBinary only lets you define a number of bits evenly divisible by 8. But bit arrays may not have a length in bits evenly divisible by 8. So, I added the Count attribute. If you don't have a number of bits evenly divisible by 8, then put a Count attribute to indicate the actual total number of bits you are attempting to represent. -- John. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
