  - ### Method Detail

    - #### getCompulsoryXmlPropertySettings

          public Collection<RioSetting<?>> getCompulsoryXmlPropertySettings()

      Returns a collection of settings that will always be set as XML parser properties using `XMLReader.setProperty(String, Object)`

      Subclasses can override this to specify more supported settings.

      Returns:
        A collection of `RioSetting`s that indicate which properties will always be setup using `XMLReader.setProperty(String, Object)`.

    - #### getCompulsoryXmlFeatureSettings

          public Collection<RioSetting<Boolean>> getCompulsoryXmlFeatureSettings()

      Returns a collection of settings that will always be set as XML parser features using `XMLReader.setFeature(String, boolean)`.

      Subclasses can override this to specify more supported settings.

      Returns:
        A collection of `RioSetting`s that indicate which boolean settings will always be setup using `XMLReader.setFeature(String, boolean)`.

    - #### getOptionalXmlPropertySettings

          public Collection<RioSetting<?>> getOptionalXmlPropertySettings()

      Returns a collection of settings that will be used, if set in `AbstractRDFParser.getParserConfig()`, as XML parser properties using `XMLReader.setProperty(String, Object)`

      Subclasses can override this to specify more supported settings.

      Returns:
        A collection of `RioSetting`s that indicate which properties can be setup using `XMLReader.setProperty(String, Object)`.

    - #### getOptionalXmlFeatureSettings

          public Collection<RioSetting<Boolean>> getOptionalXmlFeatureSettings()

      Returns a collection of settings that will be used, if set in `AbstractRDFParser.getParserConfig()`, as XML parser features using `XMLReader.setFeature(String, boolean)`.

      Subclasses can override this to specify more supported settings.

      Returns:
        A collection of `RioSetting`s that indicate which boolean settings can be setup using `XMLReader.setFeature(String, boolean)`.

    - #### getXMLReader

          protected XMLReader getXMLReader()
                                    throws SAXException

      Creates an XML Reader configured using the current parser settings.
      Returns:
        a configured `XMLReader`
      Throws:
        `SAXException` - if an error occurs during configuration.
