Right, my point was you cannot do that in 3.3 ... you are already after 
the group.properties group, but because of the processing order 
Properties shows up at the end.  Properties doesn't have an ID, so 
there's no way to say ?after=org.eclipse.properties.action.  In 3.4 
there will hopefully be additional query operations available (as 
opposed to just "after" and "before").

An example of using IElementUpdater is available in the 
org.eclipse.ui.tests plugin, ToggleContextHandler.

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.ui.tests/Eclipse%20UI%20Tests/org/eclipse/ui/tests/menus/ToggleContextHandler.java?view=co

You can see how it is used in the org.eclipse.ui.tests/plugin.xml by 
tracking the command id, org.eclipse.ui.tests.menus.toggleContext

This is a little different from your scenario, as it is implementing a 
set of toggle commands (parameterized on the specific context they toggle).

Later,
