Validation Tab
In the Validation tab, you can configure the
      validation scenarios associated with the particular framework you are editing. These validation scenarios are presented
      in the Configure Validation Scenarios dialog box when validating a
      document and you can specify which scenarios will be used by default for a particular document
        type.
    Note: 
If a main file is associated with the current file, the
      validation scenarios defined in the main file, along with any Schematron schema
      defined in the default scenarios for that particular framework, are used for the
      validation. These take precedence over other types of validation units defined in the default
      scenarios for the particular framework. For more
        information on main files, see Contextual Project Operations Using 'Main Files' Support or Modular Contextual XML Editing Using 'Main Files' Support.
