Analysis of bitOrder and byteOrder (public comment: byteOrder not sufficient to implement MIL-STD-2045-47001D)
by Mike Beckerle 11 Nov '13

11 Nov '13

I have done a fairly thorough analysis of the bit-order issue. Bit order only matters when an element constructs a value from part of a byte, or spans bytes, with a partial byte somewhere on one end, the other, or both. The attached spreadsheet walks through all the cases.

Count is 14 unresolved/undeferred public comments
by Mike Beckerle 07 Nov '13

07 Nov '13

I just marked some of the simple public comments (like broken links, typos) as Resolved - will fix. I also marked the issues that have action items and are not deferred with "Action NNN" in their subject line. What remains to discuss are 14 public comments that are neither resolved, deferred, nor have action items assigned.

Re: [DFDL-WG] possible editorial issue - Schema Definition Warning
by Cranford, Jonathan W. 05 Nov '13

05 Nov '13

On second thought, instead of a Schema Definition Warning, could this be a recoverable error instead? That is, would the following convey the originally intended meaning better? Note: Unrecognized DFDL properties or property values can produce a recoverable error, and an implementation can attempt to process data despite the error. IIRC, this section on specific errors was added *before* recoverable errors were added to the spec.

possible editorial issue - Schema Definition Warning
by Cranford, Jonathan W. 05 Nov '13

05 Nov '13

The phrase "Schema Definition Warning" only occurs once in the published 1.0.4 spec (without respect to capitalization), in Section 2.6 Specific Errors Classified: "Note: Unrecognized DFDL properties or property values can produce a Schema Definition Warning and an implementation can attempt to process data despite the warning." Is the concept of a Schema Definition Warning a nascent concept already present in the spec but not well-defined? If so, this might be a minor issue that warrants an errata. My recommendation would be that Schema Definition Warning be defined and used consistently throughout the document. Otherwise, I recommend that "Schema Definition Warning" be replaced in the above sentence with simply "warning". In this case, this is probably just an editorial issue. Very respectfully, -- Jonathan W. Cranford Senior Information Systems Engineer The MITRE Corporation (http://www.mitre.org)
