And what will be the correct one? 

Do you want to go back to \upshape +\mdseries?

Or do you want to go back to the font of "I'm normal" regardless
what this font was (e.g. even if it was \slshape or \scshape or of
"light series".)?

And in the first case: what should <object type="tNormal"> give if
in the surrounding context there is also a change of family like
\textsf?
