- public class DocTypeReader 
- extends java.io.Reader
The DocTypeReader can be used to dynamically include a
 DOCTYPE declaration in an XML stream. Often it is
 inconvenient to specify a DOCTYPE in XML files -- you many
 want the option of parsing the files without reading the DTD, the files
 may move around, making placing a DOCTYPE path to the DTD in
 them unattractive, and you may have many files, making an in-line include
 of the DTD unattractive as well. This class makes
 it possible to maintain XML files without any DOCTYPE
 declaration, then dynamically include the DOCTYPE information
 at runtime.
 If the XML stream already contains a DOCTYPE declaration,
 the reader will not add an additional one.
 The DOCTYPE information given to the reader will be placed
 in the XML stream it wraps just before the root element of the document.
 Note that all methods other than the various forms of read
 apply onto the underlying XML stream and should not be used until the
 header and doc type have been read.

              throws java.io.IOException
- Construct the reader with an XML stream, and set the
 DOCTYPEinformation to be included. The given
 reader should access an input source containing the exact declaration
 to include, such as:
 <DOCTYPE schedule SYSTEM "schedule.dtd">
 <DOCTYPE html PUBLIC "-//W3C//DTD XHTML ...>
 <DOCTYPE stock-price [ <ELEMENT symb ... ]>
 If the reader is null, noDOCTYPEinformation will be
 included in the stream.
