updated RNC schema to include some Deliberation modules
dr.rnc now “includes”
  unordered
  stripe-skipping
  default_inf
  default_absent
  default_present
  equal
  oriented_attrib
  oriented_non-default
  oriented-default
  type
  init
  explicit_datatyping
  dataterm_simple
  data_simple_content
  dataterm_any
  data_any_content
  skolem
  individual
  variable
  xml_base
  xml_id

The components defined in these modules have had their definitions removed from dr.rnc .  This includes
  node.attrib
  xml.attlist
  declare.attlist
  torso.attlist
  degree.attlist
  Ind
  Data
  Var
  Skolem
  Reify
  repo.attlist
  resl.attlist
  Equal
  weak.attlist
  strong.attlist

Many start options were removed - is there a reason these elements should be global?  (XSD makes them that way by default, so that’s how they get translated into RNC, but in RNC we have a choice.)
I kept the start’s for the performatives - this was useful in the xi:include example.
