 * This interface has methods associated with the XSLT xsl:output attribues

 * In an XSLT stylesheet these attributes appear for example as:
 * <pre>
 * <xsl:output method="xml" omit-xml-declaration="no" indent="yes"/> 
 * </pre>
 * The xsl:output attributes covered in this interface are:

 * doctype-system
 * cdata-section-elements
 * indent
 * media-type
