[MathML3-last-call] RTL and mlabeledtr

I didn't see anything that said what to do with the label for mlabeledtr.
In fact, it doesn't say what to do with the main table elements although it
is not hard to guess given what it says in mtr, but it probably should be
explicit.  For the label, mtable's "side" attr controls the placement, so if
something should be done for RTL, that seems like that's where a statement
should be made.
