  XSLProcessorVersion | Deprecated To be replaced by org.apache.xalan.Version.getVersion()
  XSLTAttributeDef | This class defines an attribute for an element in a XSLT stylesheet, is meant to reflect the structure defined in http://www.w3.org/TR/xslt#dtd, and the mapping between Xalan classes and the markup attributes in the element.
  XSLTElementDef | This class defines the allowed structure for an element in a XSLT stylesheet, is meant to reflect the structure defined in http://www.w3.org/TR/xslt#dtd, and the mapping between Xalan classes and the markup elements in the XSLT instance.
  XSLTElementProcessor | This class acts as the superclass for all stylesheet element processors, and deals with things that are common to all elements.
  XSLTSchema | This class defines the allowed structure for a stylesheet, and the mapping between Xalan classes and the markup elements in the stylesheet.

## Package org.apache.xalan.processor Description

Parses an XSLT stylesheet document (which may include and import other stylesheet documents) and produces a StylesheetRoot (a TRaX Templates object).

StylesheetProcessor implements the TRaX `TransformerFactory` interface, as well as the `SAXTransformerFactory` interface. It registers the `StylesheetHandler` object (a TrAX `TemplatesHandler` implementation) as the SAX ContentHandler for an XMLReader, and uses the XMLReader to parse the stylesheet document.

Before parsing the XSLT input, StylesheetHandler assembles an `XSLTSchema`, which uses `XSLTElementDef` and `XSLTAttributeDef` objects to recursively define the elements and attributes that an XSLT stylesheet may contain. The StylesheetHandler then passes on each parse event to the `XSLTElementProcessor` which the XSLTElementDef assigned to the element associated with that event.
