    - #### cdata

          public void cdata(String content)

      Description copied from interface: `MarkupWriter`
      Adds parsed character content. This will be enclosed in a CDATA block if supported. When not supported, this is the same as `MarkupWriter.write(String)`.

      Description copied from interface: `MarkupWriter`
      Writes the text as a child of the current element.
      Specified by:
        `write` in interface `MarkupWriter`

    - #### writef

          public void writef(String format,

    - #### attributes

          public void attributes(Object... namesAndValues)

      Description copied from interface: `MarkupWriter`
      Adds a series of attributes and values. Null values are quietly skipped. If a name already has a value, then the new value is ignored.
      Specified by:
        `attributes` in interface `MarkupWriter`

    - #### element

          public Element element(String name,
                                 Object... namesAndValues)

      Description copied from interface: `MarkupWriter`
      Begins a new element as a child of the current element. The new element becomes the current element. The new Element is returned and can be directly manipulated (possibly at a later date). Optionally, attributes for the new element can be specified directly.
      Specified by:
        `element` in interface `MarkupWriter`
      Parameters:
        `name` - the name of the element to create
        `namesAndValues` - an even number of values, alternating names and values
      Returns:
        the new DOM Element node
      See Also:
        `MarkupWriter.attributes(Object[])`

    - #### writeRaw

          public void writeRaw(String text)

      Description copied from interface: `MarkupWriter`
      Writes raw text, text with existing markup that should be passed through the client without change. This can be useful when the markup is read from an external source (a file or a database) and is simply to be included.
      Specified by:
        `writeRaw` in interface `MarkupWriter`
      See Also:
        `Raw`

      Specified by:
        `comment` in interface `MarkupWriter`
