Make sure directiveAttributes are actually supplied and added to the directive
otherwise gmd:contact and gmd:pointOfContact (ie. all users of
gmd:CI_ReponsibleParty)cannot set the role when adding the snippet
Supply directiveAttributes parameter in iso19139 (and thus all derivatives
that don't redefine this template ie. iso19139.anzlic etc etc)
Add directiveAttributes to users of gmd:CI_ResponsibleParty to enable
role to be set
