 Oasis Changes
  A number of changes have been adopted by OAsis, including the Public

  etc.)

  New, normative documents are now required to be submitted to the TC
  Chair(s) and the appropriate document template will be provided.

IV. Guest Presentation

  Discussion: Paul noted that there have been some ontological
  discussions on Attributes that may be applicable to this solution.
  Mike Davis voiced interest in exploring this direction as well. 

  H17 noted that they developing simple hierarchical ontologies using
  OWL to the healthcare space.

  Tony raised a question on how anonymized Predicates may be assigned
  to a Subject without compromising anonymity.

  David Chadwick offered that a solution he is working with relies upon
  a localized PIP to address credential validation. Greg noted that
  this is for Attribute values only and not Predicates.

  Paul suggested that the proposed insertion of Conditions into a SAML
  assertion is a concern because they are not the these are not the same
  logical data types.
