****************************************************************
Topic: Previous Actions
****************************************************************


ACTION (20220222-01): NDW to make a proposal for possible error codes
(issue #44).

ACTION (20220222-02): Steven to outline examples in the spec. to
differentiate static and dynamic errors (issues #25, #18, #23, #31).

ACTION (20220222-03): Steven - Issue #47 - @root (Outermost effective
nonterminal as attribute) - to be proposed in the spec as a dynamic
error.

ACTION (20220222-04): Steven - simplify the spec to require the output
of 'well-formed' XML. Does that have some subcodes in terms of the
violation of well-formedness.  (Issues #25, #18, #23, #31, #47.)

ACTION (20220222-05): Steven Issue #33 (s = @a, b, @c) - this needs to
be explicit.

ACTION (20220222-06): NDW Issue #45 (Unused non-terminals) - NDW - two
test suites - undefined and unused.  Pull request awaiting review.

    https://github.com/invisibleXML/ixml/issues/21


Topic: Issue #25 Static and dynamic errors?

    https://github.com/invisibleXML/ixml/issues/25

    Clarification needed: may a processor reject a grammar statically
    because a dynamic error may arise for some inputs?  Or only if a
    dynamic error will arise for any input?

Topic: Terminological issues: what is an 'error'?

    Is it an 'error' for the input string not to be a sentence in the
    language described by the input grammar?  Agenda item requested by

    See https://lists.w3.org/Archives/Public/public-ixml/2022Feb/0085.html
    and the surrounding thread

Topic: Pragmas proposal (continued) (issues #10, #29, #30)

    Brief summary of TM proposal:
    https://lists.w3.org/Archives/Public/public-ixml/2022Jan/0029.html

    Proposal: misc/pragmas-proposal.md in proposal-pragmas branch:
    https://github.com/invisibleXML/ixml/blob/proposal-pragmas/misc/pragmas-proposal.md

    Background: misc/pragmas.md in proposal-pragmas branch:
    https://github.com/invisibleXML/ixml/blob/proposal-pragmas/misc/pragmas.md

    (This is a longer discussion of the proposal, with alternatives;
    discussion of requirements, desiderata, and design principles; and
    worked examples showing how processors might use the pragmas
    proposal for support of various kinds of additional functionality.)

    Strawman proposal from SP:
    https://lists.w3.org/Archives/Public/public-ixml/2022Jan/0102.html

    Specific issue:  is there a reason for pragmas to nest?
    https://github.com/invisibleXML/ixml/issues/30

    Specific issue: are the constraints on what a pragma can change or do?
    https://github.com/invisibleXML/ixml/issues/29

    During the discussion, Dave Pawson asked that the application of
    pragmas to parse trees be an agenda item:

****************************************************************

Normal date for ixml meetings is every Tuesday at 15:30 UTC

On the usual schedule, the next meeting would be Tuesday 22 March, at
15:30 UTC for one hour; the U.S. is on DST on that date, so the times
in the U.S. are one hour later than usual.

https://www.timeanddate.com/worldclock/fixedtime.html?msg=ixml+online+meeting&iso=20220315T1530

N.B. Most of the U.S. shifted to Daylight Savings Time on Sunday 13
March 2022.  Most of Europe will shift to summer time on Sunday 27
March 2022.

Expected scribe next week:  volunteers sought.

[For the record: we have regrets from SP for 8 March, from JL for 8
and 15 March.]

[For the record: the current state of the minute-taking rota is:

  Steven Pemberton   2022-01-25
  Norm Tovey-Walsh   2022-02-08
  M Sperberg-McQueen 2022-02-15
