Because if another part loads expat then you'll have conflicts, and a 
segfault. The modperl and axkit lists get segfault reports several times a 
week from people trying to use XML::Parser (which links to expat too). The 
expat that comes with Apache is not a shared library, and thus plays poorly 
with other apps running atop Apache and using expat (mod_perl, PHP, etc...). 
There was talk of moving expat out of Apache (it'd only get linked if 
needed), eg http://archive.covalent.net/new-httpd/2000/10/0170.xml, but it 
didn't happen.

Of course ! But it should be made available in a way that does not cause 
conflicts, that would make it a much nicer thing to want.
