MikeB, Geoff Judd, Alan Powell attended. Continued through SP's comments. sp37 - got it. sp45 - agree. This whole part to be rewritten. sp115 - ok. strict and "lax" as enums. No built-in default - we never use defaults in the processor itself. Only in the predefined formats. sp118 - ok sp123 - Proposal to simplify length, lengthKind, lengthUnits, and also occursKind, occursPath, occursPathUnits needed. (along the lines of byteCount, itemCount, length='delimited' enum, etc.) sp154 - Need specific proposal to eliminate hexBinary and use what for opaque (consider also string with encoding='bytes'. ) Or introduce a dfdl:byteString type or dfdl:opaque type. (derived type - just a standard name). sp158 - see sp123 sp165 - needed to have composition property for enclosing groups and or end-of-data. Regexp doesn't fix this.
