I think in practice it just uses whatever string you put in the DTD
SYSTEM identifier.

Unlike other URI it doesn't seem to be automatically resolved angainst
any base.

XSLT2 says it returns the system id from the data model and teh data
model says

http://www.w3.org/TR/xpath-datamodel/#dm-unparsed-entity-system-id

The dm:unparsed-entity-system-id accessor returns the system identifier
of an unparsed external entity declared in the specified document. I

Note that this is _not_ defined to be a URI, but defined to be a "system identifier"

XDM defines "system identifier" in section 6.5.1 to be "The system identifier of the entity."
which is getting a bit circular,

but infoset defines it
http://www.w3.org/TR/xml-infoset/#infoitem.rse
here as

[system identifier] The system identifier of the entity, as it appears
in the declaration of the entity, without any additional URI escaping
applied by the processor.

so I think that confirms that you should get back the DTD-provided
string.
