Infrastructure for working with an XML parser.

An implementation of the {@link org.apache.xalan.xpath.xml.XMLParserLiaison} interface provides a liaison between the XSLT processor and an XML parser. Unless you specify an XML parser and your own implementation of the XMLParserLiaison interface, Xalan-Java uses the {@link org.apache.xalan.xpath.xml.XMLParserLiaisonDefault}:

This package also includes four implementations of the SAX org.xml.sax.DocumentHandler interface:

• {@link org.apache.xalan.xpath.xml.FormatterToDOM}
• {@link org.apache.xalan.xpath.xml.FormatterToXML}
• {@link org.apache.xalan.xpath.xml.FormatterToHTML} (an extension of FormatterToXML)
• {@link org.apache.xalan.xpath.xml.FormatterToText}
