Manifest Section configuration does not work properly

The documentation at http://maven.apache.org/plugins/maven-assembly-plugin/usage.html states..."the Assembly Plugin supports configuration of an <archive> element which is identical to that supported by the maven-jar-plugin"

However when I add a manifestEntries section just like I have in my maven-jar-plugin configuration, it is ignored by the assembly plugin. The manifest section works but not manifestEntries.

I need both sections to work as documented.
