/**
 * This class represents an output destination for data.
 * This interface allows an application to encapsulate information about an
 * output destination in a single object, which may include a URI, a byte stream
 * (possibly with a specifiedencoding), a base URI, and/or a character stream.
 * The exact definitions of a byte stream and a character stream are binding
 * dependent.
 * The application is expected to provide objects that implement this interface
 * whenever such objects are needed. The application can either provide its
 * own objects that implement this interface, or it can use the generic factory
 * method DOMImplementationLS.createLSOutput() to create objects that
 * implement this interface.
 * The DOMSerializer will use the LSOutput object to determine where to
 * serialize the output to. The DOMSerializer will look at the different
 * outputs specified in the LSOutput in the following order to know which one
 * to output to, the first one that data can be output to will be used:
 * 1.LSOutput.characterStream
 * 2.LSOutput.byteStream
 * 3.LSOutput.systemId
 * LSOutput objects belong to the application. The DOM implementation will
 * never modify them (though it may make copies and modify the copies,
 * if necessary).
