/* In 2001, this was part of the Expat package. We copied it into
Xmlrpc-c because it's easier on the user than making him get and
link Expat separately, and we don't expect to benefit from separate
maintenance of Expat.
But we changed all the external symbols that in Expat are named
"XML_xxxx" to "xmlrpc_XML_xxxx" because people do link Xmlrpc-c
libraries into programs that also link Expat (a good example is
where an Apache module uses Xmlrpc-c). We don't want our names to
collide with Expat's.
