"<<ALL FILES>>" in plugin descriptor is invalid XML

I recently upgraded my Eclipse install, and it is now telling me that the following (which appears in lots of plugin descriptors) is invalid XML:

<permission class="java.io.FilePermission" name="<<ALL FILES>>" actions="read,write,delete"/>

The '<' and '>' characters in the name attribute should use character entities; i.e. "&lt;" and "&gt;". Fortunately, NanoXML doesn't seem to care about this. But it should be fixed.
