1.6.2. Merge without discussion

   uncontroversial when the agenda was prepared. The chairs propose that
   these can be merged without discussion. If you think discussion is
   necessary, please say so.
     * PR [39]#1760: Remove hand-generated diffs from the builds
     * PR [40]#1759: Fix validation issues in the EXPath module function
       catalogs
     * PR [41]#1743: 1738 Formatting of Notes in F&O
     * PR [42]#1741: 1739 drop references to ordering mode in the static
       context
     * PR [43]#1734: 1682 Type promotion and operator mapping

   Proposal: merge these PRs without discussion.

   Accepted.

       two strings
     * Issue [45]#1571: Discussion: On the implementability of the specs
       and helping implementors

   Proposal: close these issues without further action.

   Accepted.

1.6.4. Substantive PRs

   The following substantive PRs were open when this agenda was prepared.
     * PR [46]#1753: 1750 Overhaul of EXPath binary spec
     * PR [47]#1746: Replace processing model diagrams

2. Technical agenda

2.1. PR #1753: 1750 Overhaul of EXPath binary spec

   See PR [48]#1753.
     * JWL: Jirka and I have both gone through it. It seems fine; there
       are good formal definitions now. We've also done a first pass at
       getting errors corrected. There are still a copy of tiny little
       things. (Wrong error code, for example.)
          + ... Encourage you to look through; there are some nice 4.0
            syntax "tricks" that make the definitions easy to use and
            understand.
          + ... There are no additions; there have been a few things
            trimmed, but there's very little backwards incompatibility.

   Some discussion about when we agreed to take this on.
     * RD: Some of the functions have an additional fn: prefix.
     * JWL: Those are probably construction operations, piggybacking off
       stuff in the F&O stylesheets.

   ACTION: QT4CG-108-01: JWL look at the extra fn: prefixes introduced by
   the stylesheets in the binary spec

   Proposal: Accept this PR.

   Accepted.

2.2. PR #1746: Replace processing model diagrams

   See PR [49]#1746.

   NW shows the diagrams
     * JWL: Is this SVG? Do we have the sources?
     * NW: Yes, they're made with GraphViz and checked in the sources.
     * JK: Is there any checking for alignment when things change?
     * NW: No, alas.
     * RD: Can we have links now and tool tips for SQ1 etc.?
     * NW: Yes. Good idea.

   TION: QT4CG-108-02: NW to add links and tooltips to the new processing
   model diagrams

   Proposal: Accept this PR.

   Accepted.

2.3. Some discussion of the table of contents

     * DN: Thank you for the expandable/collapsable table of contents.

   Some discussion of whether there might be outstanding performance
   issues in the JavaScript, especially with respect to the widget that
   opens/closes the ToC.

   If you have an issue, please open an issue.

2.4. Issue triage

   Using the PRG-* tags seems like it would be inviting confusion. New
   tags proposal:
     * Reviewed-required, this is a required feature; we can't progress
       without it.
     * Reviewed-optional, this is an optional feature we're still hoping
       to finish.
     * Reviewed-close, this is an optional feature that we'd like to have,
       but we're going to abandon it if no one provides a detailed change
       proposal. (This category implies "close without further action" at
       the next meeting.)
     * Reviewed-easy, Reviewed-hard, optional tags indicating the
       consensus intuition about how difficult it would be to address the
       issue.

   There are 70 untriaged issues. We can start at the top, or the bottom,
   or with nominations for "easy to categorize" issues.

2.4.1. Issue 75

   Issue [50]#75: Support processing HTML 5 template element content
     * RD: I think it's useful to have open. From the discusions that we
       had, I think we can defer it.
     * DB: Do we also have a "meritorious but we need someone to do it"
     * NW: Yes, I can do that.
     * DN: Alternatively, we could make a time when people can present
       their issues.
     * NW: No. They were on the agenda.

   Reviewed-optional
     * RD: It would be nice to have feedback from people using parse-html
       if the current mechanisms are sufficient.

2.4.2. Issue 158

   Issue [51]#158: Support optional parameters on dynamic functions
     * RD: I'm happy for this to be optional or closed.
     * DN: I think we should know what prevented the original author from
       preparing a PR.
     * RD: I created this ticket as a result of discussions in one of the
       meetings; based on a comment from DN, I believe.

   Reviewed-optional

2.4.3. Issue 285

   Issue [52]#285: Stability of collections
     * CG: This is about how much latitude implementations have for
       returning collections in a particular order.
     * JLO: I think that it would make sense to make collections
       nondeterministic.

   Reviewed-optional

2.4.4. Issue 322

   Issue [53]#322: Map construction in XSLT: xsl:record instruction
     * JWL: Can we look at this next week?
     * JK: If a member of the group wishes to avoid assigning a label,
       then it should come with action.

2.4.5. Issue 576

   Issue [54]#576: JSON serialization: INF/NaN, function items

   Reviewed-optional
     * Issue [55]#583: (array|map):replace -> *:substitute or *:change
     * CG: This is just a question of whether we want a map:replace
       function?
     * JLO: We have specified array and map replace.
     * CG: Yes, but the idea from MK was that we could replace them with
       map:substitute. But it's been two years.
     * DN: Almost no one knows what this is. It would be better to wait
       until next week.
     * CG: I suggest we attempt to close this one.

   Reviewed-optional

   Chair declares the triage exercise a fail for this week. Will put a
   shorter set of issues on the list next time with the expectation that
   members will come prepared to triage them.
     * JWL: Take all the XSLT once and push them next week.

3. Any other business

   None heard.
