Document Type Association
In general terms, a Document Type Association is a set of rules that
    associate a document type with a framework. In Oxygen XML Author Eclipse plugin, Document Type
        Association also specifically refers to a preferences page where you can create new custom frameworks or edit
    existing ones. Note that frameworks (document types) that come built-in with Oxygen XML Author Eclipse plugin are read-only, but you can Extend or Duplicate them to configure them as custom
      frameworks.
