sax :: SAXLocator :: system_id
Return the system identifier of the document
entity or of the external parsed entity in which the markup
triggering the event appears.
Return null if no system identifier is available.
If the system identifier is a URL, the parser must resolve it
fully before passing it to the application. For example, a file
name must always be provided as a file: URL, and other
kinds of relative URI are also resolved against their bases.
# Return the system identifier for the current document event.
