Since I’ve not seen any comments so far I’ll add my thoughts inline:
1. There are two combinations of these attributes that I don't know what to do with. As far as I'm concerned, it makes no sense to use the pairs @from & @notBefore or @to & @notAfter. That said, some *might* argue that using three of the four (either @from with @notBefore & @notAfter, or @to with @notBefore & @notAfter) does make sense. (Specifying a duration that starts at @from and ends sometime in the range specified by the other two, or that ends at 3A@to and starts sometime in the range specified by the other two.) So: a) What should I put for the makes-no-sense pairs? b) Should I be writing prose to support the ( (@from|@to), @notBefore, @notAfter ) encoding? Or is that too wild? Or is there some other interpretation we should be considering? ad a) I’m not able to recall the whole discussion but I wonder if everyone was agreeing that these are nonsense? If we said they were nonsense we should add a schematron rule and make it explicit in prose. We should as well(?) restrict the combination of @when with any other attribute from att.datable.w3c ad b) Yes. Some James Cummings wrote on the ticket: "It is clear to me at least that as soon as you have @from or @to you have a duration and the other notBefore/notAfter then applies to the imprecision of the missing from/to attribute.“
2. Since order of attribute specification is inconsequential, and an attribute may only be specified once, making a full 4x4 table of these attributes results in 4 cells that make no sense because they are for the same attribute twice, and each of the other unique 6 cells is duplicated (for a total of 16 cells). A B C D A XX ba ca da B ba XX cb db C ca cb XX dc D da db dc XX Should we display all 16 cells? Or make an abbreviated chart, e.g.: A B C D A XX -- -- -- B ba XX -- -- C ca cb XX -- D da db dc XX Or, noting that in the above chart row A and column D are useless, make a truncated chart, e.g.: A B C B ba XX -- C ca cb XX D da db dc If you look at the draft of the chapter I have at the moment (http://paramedic.wwp.neu.edu/~syd/temp/TEI_Council/html/ND.html#NDATTSda) you'll see that there several (ugly) versions of this table. Which one should we use? The smaller, the better. And I’d add a note that the combination of any of these attributes with @when is nonsense …
3. The default HTML styling of <table>, <tr>, and <td> is not good for this purpose, and I see no easy way to special-case this. (Putting @style on <td>, and maybe <tr>, does not work; the attribute does not get propagated to the HTML.) Does anyone know of a way around this, or already know where in the Stylesheets I should be working to get @style working? If you take a look at http://paramedic.wwp.neu.edu/~syd/temp/TEI_Council/test-table-of-attrs-layou..., you'll see a set of tables closer to what I think they should look like.
I don’t know. Best Peter
