I think I can guess what happens here, but from the outside the suspensions look odd. I wonder if that case happens elsewhere too and should get some sort of an interface, or at least perhaps a sentence or two explaining what goes on.

[u-fischer]

I can add a sentence, but I have no idea for a better interface. One doesn't want the tagging from the minipage environment and imho this can only be done either by surrounding the minipage with such a code, or by defining a dedicated environment minipagewithouttagging.

[FrankMittelbach]

I think the question to ask is under which circumstances do you not want minipage tagging? Because of it being inside an lrbox/mbox? What should happen if you have an lrbox with 2 minipages inside?

[FrankMittelbach]

point is use of lrbox is core LaTeX so the combination with minipage should work. without the need to disable and reanable tagging by the user

[u-fischer]

I do not want the minipage tag (the Div) because I'm in a float and this minipage has no semantic meaning. I do not want the \tagmcend\tagstructend before the minipage (which normally closes a P-tag) and the reopening after the minipage as the minipage is in a lrbox and fills it up. Two minipages (without other material) should probably use a Div around them.

Well the problem is that xxx minipage yyy in a lrbox needs different tagging to minipage alone. (At least with pdflatex which has to insert correctly nested MC-literals.)

this looks OK to me modulo the discussion re minipage tagging when I'd defer to whatever @FrankMittelbach and @u-fischer decide.

[FrankMittelbach]

Well, eventually a minipage inside an lrbox has to work as this is official std LaTeX usage and should not require any action by a user if that is used in a document. However, that isn't soemthing we need to solve now. But what we should do is making an issue for it in the tagging-project repo, so that it gets address at some point.

So with that I think this PR can be merged

[FrankMittelbach]

approved but we should open an issue for minipage inside lrboxes
