JAXP is pretty unspecific about this. The description of
SAXResult.setSystemId() is "Set the systemID that may be used in association
with the ContentHandler." which tells you next to nothing. I think it is
best to regard the JAXP concept of "system ID" as representing the base URI
of nodes reported through the SAX interface.

Equally, the description of the Locator object in the SAX specification says
nothing about how the location should be set in the case of documents that
don't originate directly by parsing lexical XML. In Saxon, the Locator
passed to the ContentHandler for the result tree always reflects the
location in the stylesheet of the instruction that generated the element or
attribute in question. This information is used by debuggers and IDEs that
do back-mapping, and also by Saxon itself when you request schema-validation
of the result document.
