Bad entities

[Julian Bond <julian_bond@voidstar.com>]

In the last few days, I've seen a few rss feeds that have malformed XML
due to non XML entities in encoded html in the <description> element.
These are almost always perfectly valid html entities.

Looking at http://www.webreference.com/xml/reference/xhtml-lat1.txt it
appears that there's a way of adding an entry in the xml file that more
or less says "Support xhtml entity definitions". But I don't quite
understand the syntax. Can someone throw some light on this and suggest
exactly what RSS writers should add to their files?
