Hello Arno,

This is what l3keys2e is for: l3keys does the 'LaTeX3' side, l3keys2e 
does the 'LaTeX2e interface' part. You want

   \RequirePackage{l3keys2e}
   \ProcessKeysOptions{<module>}

or

   \RequirePackage{l3keys2e}
   \ProcessKeysPackageOptions{<module>}

depending on whether global options should be parsed.
