Subject: 24.4; nxml-mode: DTD edition breaks the file structure
Date: Tue, 28 Oct 2014 15:34:33 +0100

Consider the following XML file:

------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE root [
<!ELEMENT root (item)*>
<!ELEMENT item (#PCDATA)>
]>

<root>
<!-- 1234567890 1234567890 1234567890 1234567890 1234567890 -->
</root>
------------------------------------------------------------------

1. Open it with "emacs -Q".
2. Go to line 2 and type C-SPC.
3. Go to line 6 and type C-w to delete the DTD.

The highlighting gets completely wrong. And if I delete the closing
tag </root> (with C-k) and type C-c C-f, I get the error:

  No matching start-tag

In more complex files, slightly editing the DTD gives the same behavior.
