I suppose you can get help with the syntax here: http://wiki.eclipse.org/Query_Language_for_p2

Note: You do *not* want to use "metaRequirements", but rather regular "requirements". Meta requirements are for requirements on the installer/director and not for requirements of your artifact. When using metaRequirements, your installation will be broken when using a separate runtime for the director.

AFAIK, you got this working, right?
