nXML highlighting problem

[Allin Cottrell]

I'm using GNU Emacs 26.3 and current nxml on Arch Linux. A fairly
recent update (sorry, can't date it exactly) has brought a change in
highlighting behavior which I'd very much like to revert.

Namely, it seems that a plain apostrophe in XML text is now being
treated as a delimiter that calls for a change of face. So after the
first (single, possessive) apostrophe in the text the rest of the
document is shown in "within delimiters" mode.

I'd be grateful if anyone can tell me how to stop this from happening.
I've done C-h M but I couldn't find an answer there.
