We also need to decide on Errata 2.95 which is about whether text is implicitly 8-bit aligned.

Given that we have cases of text aligned in other ways (the 7-bit packed ascii stuff), this rule seems heavy handed and inflexible.

We could say that if alignment="implicit", then the first codepoint of any text is implicitly aligned on an 8-bit boundary. This would apply to delimiters, but also to any text that is being scanned with a regex. Subsequent codepoints of the same text are not specifically aligned. This lets us choose alignment="1", and the 7-bit packed stuff can then have syntax in it, have regex's that it must match, etc. but if alignment="implicit", then the normal, less error prone behavior of skipping to a byte-boundary would be in force.

I reviewed this.

2.108 has Change: Format annotations.... and also Remove: Format Annotations. Should just have Change.

3.13 I think we missed a couple places where the previous design where we had replacement control is still leaking into the text.

Phrase "Any character that is skipped counts as 0." should be dropped. We don't skip anymore.

Concerning:  "In the following, the match is against data where any character replacement has already taken place." The first sub-bullet about lengthKind pattern is incorrect. For lengthKind pattern I believe any decode error should cause the match to end, i.e., a pattern that matches digits only will match a string of digts followed by binary data that causes a decode error. Similarly, when matching literal nils, (character or literal value), any decode error should cause the match to fail.

Subject:        First draft of DFDL Errata v011


Please find attached the first draft of Errata v011.
This incorporates all DFDL spec errata raised since v010 (June 22 2012) until the last DFDL WG call (November 13 2012).
Change tracking: I accepted all changes from v010 so the changes you see are all due to v011.
I would appreciate a review for correctness and omissions.
Please note that some of the new errata have been best handled by updating existing related errata, so please read from start.
