                  throws IOException

Description copied from interface: IXMLWriter

Write XML declaration to document. This can only be called before any other methods in the interface are called.

Specified by:

writeXMLDecl in interface IXMLWriter

Parameters:

version - XML version text

encoding - text for encoding attribute (unspecified if null)

standalone - text for standalone attribute (unspecified if null)

Throws:
