+<p>This package implements SAX2-specific transformation APIs. It provides
+  classes which allow input from {@link org.xml.sax.ContentHandler}
+  events, and also classes that produce org.xml.sax.ContentHandler events. It
+  also provides methods to set the input source as an
+  {@link org.xml.sax.XMLReader}, or to use a
+  {@link org.xml.sax.InputSource} as the source. It also allows the
+  creation of a {@link org.xml.sax.XMLFilter}, which enables
+  transformations to "pull" from other transformations, and lets the transformer
+  to be used polymorphically as an {@link org.xml.sax.XMLReader}.</p>
+<p>The {@link javax.xml.transform.sax.SAXSource} class allows the
+  setting of an {@link org.xml.sax.XMLReader} to be used for "pulling"
+  parse events, and an {@link org.xml.sax.InputSource} that may be used to
+  specify the SAX source.</p>
+<p>The {@link javax.xml.transform.sax.SAXResult} class allows the
+  setting of a {@link org.xml.sax.ContentHandler} to be the receiver of
+  SAX2 events from the transformation. 
+<p>The {@link javax.xml.transform.sax.SAXTransformerFactory} extends
+  {@link javax.xml.transform.TransformerFactory} to provide factory
+  methods for creating {@link javax.xml.transform.sax.TemplatesHandler},
+  {@link javax.xml.transform.sax.TransformerHandler}, and
+  {@link org.xml.sax.XMLReader} instances.</p>
+<p>To obtain a {@link javax.xml.transform.sax.SAXTransformerFactory},
+  the caller must cast the {@link javax.xml.transform.TransformerFactory}
+  instance returned from
+  {@link javax.xml.transform.TransformerFactory#newInstance}. 
+
+<p>The {@link javax.xml.transform.sax.TransformerHandler} interface
+  allows a transformation to be created from SAX2 parse events, which is a "push"
+  model rather than the "pull" model that normally occurs for a transformation.
+  Normal parse events are received through the
+  {@link org.xml.sax.ContentHandler} interface, lexical events such as
+  startCDATA and endCDATA are received through the
+  {@link org.xml.sax.ext.LexicalHandler} interface, and events that signal
+  the start or end of disabling output escaping are received via
+  {@link org.xml.sax.ContentHandler#processingInstruction}, with the
+  target parameter being
+  {@link javax.xml.transform.Result#PI_DISABLE_OUTPUT_ESCAPING} and
+  {@link javax.xml.transform.Result#PI_ENABLE_OUTPUT_ESCAPING}. If
+  parameters, output properties, or other features need to be set on the
+  Transformer handler, a {@link javax.xml.transform.Transformer} reference
+  will need to be obtained from
+  {@link javax.xml.transform.sax.TransformerHandler#getTransformer}, and
+  the methods invoked from that reference. 
+
+<p>The {@link javax.xml.transform.sax.TemplatesHandler} interface
+  allows the creation of {@link javax.xml.transform.Templates} objects
+  from SAX2 parse events. Once the {@link org.xml.sax.ContentHandler}
+  events are complete, the Templates object may be obtained from
+  {@link javax.xml.transform.sax.TemplatesHandler#getTemplates}. Note that
+  {@link javax.xml.transform.sax.TemplatesHandler#setSystemId} should
+  normally be called in order to establish a base system ID from which relative
+  URLs may be resolved. 
+<p>The
+  {@link javax.xml.transform.sax.SAXTransformerFactory#newXMLFilter}
+  method allows the creation of a {@link org.xml.sax.XMLFilter}, which
+  encapsulates the SAX2 notion of a "pull" transformation. The following
+  illustrates several transformations chained together. Each filter points to a
+  parent {@link org.xml.sax.XMLReader}, and the final transformation is
+  caused by invoking {@link org.xml.sax.XMLReader#parse} on the final
+  reader in the chain.</p>
