It is version 2.1 with a number of bug fixes backported from
later versions. The "upstream" (with regards to libxsde) for
this works lives here:

https://github.com/boris-kolpackov/libexpat/tree/2.1

To preempts the question why not upgrade to the latest expat, the
reason is that later versions started sacrificing portability in
the name of security (like depending on platform-specific
date/time functions for hash seeds) which we cannot afford in
XSD/e.
