sec:amp-set-roles( $namespace as xs:string, $local-name as xs:string, $document-uri as xs:string, $database as xs:unsignedLong, $role-names as xs:string* ) as empty-sequence()
  Assigns the amp identified by $namespace, $local-name and $document-uri
  to have the roles identified by $roles-names.  Removes previously
  assigned roles.
  If an amp with the given identifiers does not exist, an error is 
  returned.
  If a role name in $role-names does not correspond to an existing role,
  an error is returned.
  If $role-names is the empty sequence, all roles assigned to the amp are 
  removed.
  If the current user is limited to granting only his/her roles,
  and $role-names is not a subset of the current user's roles, then an
  error is returned.
