--- Comment #2 from Mark Thomas <ma...@apache.org> ---
An alternative, shorter form using JSTL:

    <c:out value="&lt;span data-text=&quot;A &amp;ndash; B&quot;> &lt;/span>"
escapeXml="false"/>
    <span>A &amp;ndash; B</span>

OK. It took a few hours but I think I have got to the bottom of this. It is a
result of a bug fix that was applied to 7.0.47 onwards and all 8.0.x versions.
The bug in question is bug 55198 although that caused a number of regressions
so you'll find a number of linked bugs.

The relevant code is here:
http://svn.eu.apache.org/viewvc/tomcat/trunk/java/org/apache/jasper/compiler/Validator.java?view=annotate#l1392

I don't think this bug report indicates a further regression in the fix for bug
55198 (so I am closing this as invalid) although I'm open to spec based
arguments that it does.
(Note: A large part of the problem here is that the spec isn't very explicit
about the expected behaviour.)
