1.6.3. Substantive PRs

     * PR [37]#2394: 2361 Use upper case for encoding names; comparisons
       are case-blind

     * PR [39]#2350: 708 An alternative proposal for generators

       record
     * PR [41]#2019: 1776: XSLT template rules for maps and array

2. Technical agenda

2.1. PR #2394: 2361 Use upper case for encoding names; comparisons are
case-blind

   See PR [42]#2394.

   MK introduces the PR.
     * MK: We've always believed that encodings are case blind, it's a
       matter of saying it in the right places.
          + ... It runs across specs a fair bit.
     * MK: In F&O: a note that encoding names are compared without regard
       to case.
     * MK: Most of the other changes are to use upper case in examples and
       things.
     * JLO: The minus sign is now mandatory?
     * MK: We say that "UTF-8" has to be accepted, we don't say that
       "UTF8" without the hyphen should be rejected.
          + ... In practice, if you go down to Java or C# to get your
            encoding technology, it'll accept both.
     * JLO: Would it be interesting to have those encodings as a symbol or
       a QName so that we can reuse them?
     * MK: I'm not sure how one would do that. We could have a data type.
     * JLO: An enum?
     * MK: We don't have a way of defining an open enum.
     * CG: I guess this PR will cause with conflicts with the next one.

   We'll just have to work it out.

   Proposal: Accept this PR.

   Accepted.

2.2. PR #2362: 2355 bin:infer-encoding: further alignments

   See PR [43]#2362.
     * CG: This was caused by some observations by MK that the error
       handling wasn't clear.
          + ... I found other edge cases, so I decided to try to handle
            them like unparsed text.
          + ... I think we should change the F&O spec to refer to these
            rules.
     * CG: One note: fn:unparsed-text doesn't only look at the bytes; it
       looks at external encodings and media types.
          + ... I implemented both variants and it seemed like alignment
            would be better.

   Proposal: Accept this PR.

   Accepted.

2.3. PR #2350 / #2247: Generators: any progress to report?

   See PR [44]#2350 and [45]#2247.
     * MK: I think we need to stand back from the detail and think about
       what our strategy is here.
          + ... It probably makes sense to do that in the larger context
            of the whole project.
          + ... What's the balance between finishing and doing more.
     * DN: I have a good summary of what has been done.
          + ... (DN shares his screen)
          + ... [46]DN's comment on the PR, and following comments
     * DN: Generator record proposal introduces a first-class abstraction
       for generators.
          + ... We don't depend on implementation-dependent magic
          + ... Guaranteed that our code is portable across any XPath 4
            compliant implementation
          + ... We are ready to proceed

   Come back to do detailed review.
     * MK: I think that there's on the order of forty-two hours of work
       just in reviewing it.

2.4. PR #2019: 1776: XSLT template rules for maps and array

   See PR [47]#2019.

   Not ready for discussion.
     * MK: I'm long overdue on revising this proposal.
          + ... I think this is the biggest outstanding "must do" items.

3. Any other business

3.1. Where are we and where are we going?

     * NW: Any interest in a face-to-face meeting in Prague?

   Some interest.

   ACTION QT4CG-150-01: NW to ask Jirka for a room at XML Prague for
   Tuesday/Wednesday
     * MK: I've gone through the issues list and tagged some as
       "nice-to-have".
          + ... We have to draw a line and we'd still have a conherent
            spec without those things.
     * NW: You sound determined to move to the end game and get finished.
     * MK: I'd like to finish this in 2027 and if we're going to achieve
       that, we need to start closing down options.

   Some discussion of EXPath specs; we're doing File and Binary, but
   others that happen could be done on a different schedule.
     * WP: I think it's important to work out how big these buckets are.

   Some discussion of nice-to-have features.
     * MK: My feeling is that if we have a coherent proposal with test
       cases that we can accept, then we can take it. But if we don't,
       then it doesn't hold up the work.

   ACTION QT4CG-150-02: Everyone review the "nice to have" tags and object
   where they wish

   ACTION QT4CG-150-03: NW to setup an agenda item to review open issues
     * MK: Where are we on publishing a stable draft?
     * NW: I'm hoping to do that this week.
     * MK: What are we going to do about cleaning them up and fixing the
       status sections.
     * NW: My plan is to simply add a note to each status section saying
       that it's stable. If we wanted to clean up all the dangling
       references and such, write proper status sections, etc. I think
       that's a month's work. I'd rather not wait that long.
     * MK: Okay.
     * CG: what about [48]RUVs proposal?
     * MK: I'm torn on that one because of the parser implications.
     * NW: Yes, I've been leaving that one blocked on the assumption that
       unbounded lookahead is a non-starter.

   ACTION QT4CG-150-04: NW to see about a status update on that PR;
   possibly schedule discussion

   NW also observes that there are some unresolved questions about what
   form our final documents can take vis-a-vis W3C policies about
   Community Groups and Working Groups.
