1.6

• Adds support for provider and kind to Discovery Data Tool. The
  configuration elements can now take optional attributes providerColumn and
  kindColumn. If either of these are specified, then the resulting changeset
  set-item and remove-item elements will not have an id attribute, and instead
  will have locator, provider and kind attributes. The providerColumn and
  kindColumn are not included in the resulting set-item properties, since that
  would be redundant.
• No longer includes id column in set-item properties, since it is redundant
  to the set-item id attribute.
