/**
* 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).
