@FrankMittelbach @davidcarlisle I have now changed the taggging of presentation tables to use "normal" tags and an ARIA attribute. This works better with derivation. OK?

Looks good to me

see question about plug settings

[FrankMittelbach]

Probably better would be to move the \par command into those comands eventually (to ensure that they always behave identically (with or without tagging).

Also (not checked) but isn't \@@_sec_end:n{-10} a related command and should be in a socket rather than a hook?

Doesn't have to be done now, but there should be a TODO if this is something we should cleanup at some point.

[u-fischer]

I'm not sure if a \par inside \@@_sec_end:n is always wanted that's why I added if here explicitly (In the other cases the command is currently is used inside the sectioning commands in vmode, so a \par inside the command is not needed).

I'm not sure what you mean by sockets. \mainmatter etc are defined by the classes, so we can not simply redefine them to add a socket but have to use a generic hook. The problem was that the hook is before the \clearpage and so not necessarly in vmode.

[FrankMittelbach]

If I go from presentation back to table/tagging=on it should probably reset the plugs or not? If so the plugs have to be set also above, as this this might happen on the same group level.

If my assumption is correct, then this also needs a test case.

\__tag_tbl_enable: sets all sockets, including the begin sockets to the defaults. So the presentation mode only has to overwrite the two.

and there is a testfile (table-015-presentation in testfiles-table-luatex) which tests the switch from presentation back to normal tagging in one group.
