There's a broken interaction between unescaped '>' (ASCII 62) and
apostrophe (ASCII 39) when editing an XML file in nxml mode in emacs
26.3. (Version 26.2 was OK.)

At the first apostrophe following an unescaped '>', the font color
switches to "within delimiters" mode, and, depending on the context,
certain nxml editing commands stop working properly.

Here are two little examples. The first just shows the unwanted change
in face:

<?xml version="1.0"?>

<p>Here's some text, including the inequality 3 > 2. And here's
what happens in following text once an apostrophe comes along.
</p>

The second example shows what happens when the apostrophe is inside a
tag. If you delete the trailing "</p>" below, then try to insert it
again via the shortcut C-c C-f, it's "</tt>" that gets inserted
instead:

<?xml version="1.0"?>

<p>Here's some text, including the inequality 3 > 2. And here is an
apostrophe inside a tag: <tt>'</tt>. Plus some following text and
so on.</p>

Current master

commit fd6f4bf648c5a4417eb591a8c54b87c7c60de154
Author: Nikolaus Rath <Nikolaus@rath.org>
Date:   Fri Sep 27 01:39:13 2019 +0200

works like 26.2 (that is: correct).

But in fact on current emacs-26 (as of commit
bd0f173199c112b2b146e727f80e973e7fc12143)

there is the by Allin described (wrong) behaviour.

[Added Noam to CC because it seems a commit by him introduced this.]

To be more precise, since

commit 7dab3ee7ab54b3c2e7bc24170376054786c01d6f
Author: Noam Postavsky <npostavs@gmail.com>
Date:   Sun Apr 21 22:44:50 2019 -0400

the behaviour is as reported in the bug report.

With state of the previous

commit e4cde42657f8f91f795e6b7041dc50b896dc468d
Author: Noam Postavsky <npostavs@gmail.com>
Date:   Fri Apr 19 13:28:00 2019 -0400

the behaviour is like 26.2 and, as alredy reported, on master (and
correct).

Yes, it was one of the cases brought up in Bug#33887.  For the 26.3
release, we were juggling several bugs, fixes, and fixes which caused
bugs.  This case ended up broken.  We're not planning any more 26.x
releases, so I don't think there is anything more to do about this bug
now.
