                                 throws java.lang.IllegalArgumentException

      This method is used to set or override the value of the effective xsl:output attribute values specified in the stylesheet.

      The recognized standard output properties are:

      - cdata-section-elements
      - doctype-system
      - doctype-public
      - indent
      - media-type
      - method
      - omit-xml-declaration
      - standalone
      - version

      For example:

             tran.setOutputProperty("standalone", "yes");

      In the case of the cdata-section-elements property, the value should be a whitespace separated list of element names. The element name is the local name of the element, if it is in no namespace, or, the URI in braces followed immediately by the local name if the element is in that namespace. For example:

           tran.setOutputProperty(
             "cdata-section-elements",
             "elem1 {http://example.uri}elem2 elem3");

      The recognized Xalan extension elements are:

      - content-handler
      - entities
      - indent-amount
      - line-separator
      - omit-meta-tag
      - use-url-escaping

      These must be in the extension namespace of "http://xml.apache.org/xalan". This is accomplished by putting the namespace URI in braces before the property name, for example:

             tran.setOutputProperty(
               "{http://xml.apache.org/xalan}line-separator" ,
               "\n");

        `setOutputProperty` in class `Transformer`
      Parameters:
        `name` - The property name.
        `value` - The requested value for the property.
      Throws:
        `java.lang.IllegalArgumentException` - if the property name is not legal.
      See Also:
        `OutputKeys`

    - #### setOutputProperties

          public void setOutputProperties(java.util.Properties oformat)
                                   throws java.lang.IllegalArgumentException

      Set the output properties for the transformation. These properties will override properties set in the templates with xsl:output.

      If argument to this function is null, any properties previously set will be removed.

      Set the recursion limit. Used for infinite loop check. If the value is -1, do not check for infinite loops. Anyone who wants to enable that check should change the value of this variable to be the level of recursion that they want to check. Be careful setting this variable, if the number is too low, it may report an infinite loop situation, when there is none. Post version 1.0.0, we'll make this a runtime feature.
      Parameters:
        `limit` - A number that represents the limit of recursion, or -1 if no checking is to be done.

          public boolean getFeature(java.lang.String name)

                                    SAXNotSupportedException

      Look up the value of a feature.

      The feature name is any fully-qualified URI. It is possible for an TransformerFactory to recognize a feature name but to be unable to return its value; this is especially true in the case of an adapter for a SAX1 Parser, which has no way of knowing whether the underlying parser is validating, for example.

      ### Open issues:

      #### Should getFeature be changed to hasFeature?

        Keith Visco writes: Should getFeature be changed to hasFeature? It returns a boolean which indicated whether the "state" of feature is "true or false". I assume this means whether or not a feature is supported? I know SAX is using "getFeature", but to me "hasFeature" is cleaner.
      Parameters:
        `name` - The feature name, which is a fully-qualified URI.
      Returns:
        The current state of the feature (true or false).
      Throws:
        `SAXNotRecognizedException` - When the TransformerFactory does not recognize the feature name.
        `SAXNotSupportedException` - When the TransformerFactory recognizes the feature name but cannot determine its value at this time.
        `SAXNotRecognizedException`
        `SAXNotSupportedException`
