I think it is unsignedByte only, for symmetry with setBits.

I think the stable design points are any of these: * unsignedByte only * unsignedByte and byte only * types xs:long and xs:unsignedLong and any of their sub-types. * any integer at all ...mike -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com -- dfdl-wg mailing list dfdl-wg@ogf.org https://www.ogf.org/mailman/listinfo/dfdl-wg Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
