Requires FreeMind from http://freemind.sourceforge.net/wiki/index.php/Download Parsing: Writing: tbd Notes: - Precedence is from top to bottom recursively, so the top priority is dfdl:inputValueCalc, then dfdl:byteOrder, then dfdl:encoding, then it's children top to bottom, then dfdl:occursKind (you get the idea). Questions arising: - Does dfdl:escapeScheme apply when dfdl:lengthKind = endOfData ? - Confirm that only signed logical number can have a signed rep, and only unsigned logical number can have an unsigned rep ? (change from spec 028 to 030) - Should dfdl:terminator, dfdl:separator and dfdl:occursSeparator be lists (to handle alternative delimiters) ? (viz dfdl:nullValues) - Why isn't dfdl:nullIndicatorIndex encompassed by dfdl:nullIndicatorPath ? - Use of enum 'xpath' for dfdl:nullKind.? We've used "explicit" elsewhere and decorated syntax to indicate xpath for other properties. For nullKind maybe a better enum would be "external" or "remote" ? - The advanced text delimiter supplement needs revision - most of its content appears to be in the core. Main question is on prefix v infix v postfix separators and how that capability is to be specified.
