/**
* This interface represents an input source for data.
* This interface allows an application to encapsulate information about
* an input source in a single object, which may include a public
* identifier, a system identifier, a byte stream (possibly with a specified
* encoding), 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.createLSInput()
* to create objects that implement this interface.
*
The LSParser will use the LSInput object to
* determine how to read data. The LSParser will look at the
* different inputs specified in the LSInput in the following
* order to know which one to read from, the first one that is not null and
* not an empty string will be used:
*
* -
LSInput.characterStream
*
* -
*
LSInput.byteStream
*
* -
LSInput.stringData
*
* -
*
LSInput.systemId
*
* -
LSInput.publicId
*
*
* If all inputs are null, the LSParser will report a
* DOMError with its DOMError.type set to
* "no-input-specified" and its DOMError.severity
* set to DOMError.SEVERITY_FATAL_ERROR.
*
LSInput objects belong to the application. The DOM
* implementation will never modify them (though it may make copies and
* modify the copies, if necessary).
*
See also the Document Object Model (DOM) Level 3 Load
and Save Specification.
