That's becoming increasingly clear.

This isn't clear at all.

There is no such thing as a 'XML public identifier' (unless NIH also
includes comprehensive reinvention of terminology.)  I believe you're
refering to Formal Public Identifiers.

To reflect the reality of a mapping being convenient for operational
purposes.  That's the fundamental distinction between PUBLIC and
SYSTEM.   $system_id = $catalog{$public_id}

From:

  http://www.oasis-open.org/cover/sotr9401-a2.html

:  The SYSTEM keyword indicates that an entity manager should use the
:  associated storage object identifier to locate the replacement
:  text for an entity whose external identifier's system identifier is
:  explicitly specified by the system identifier.

According to the TR, 'sysid2' is a "storage object identifier" and
thus oridinarily a FSI (Formal System identifier.)
