It all depends on how you link libxml2.

If you link dynamically, this may cause problems if the client code
links dynamically with a more recent (or older) libxml2, and your
call to xmlCleanupParser could affect your client code.

If you link statically, there is no problem - all calls are resolved
when building your DLL, so there should be no unexpected interaction
with client code.

To me, this makes static linkage seem like the best approach for using
libxml in a DLL.
