So, it is left up to the system to create, but libxml2 expects the system to 
create it in a particular place yes?

I wasn't meaning to imply I wanted to put it anywhere else :)  I wanted to know 
if I needed to deal with it possibly being somewhere else.

Part of the difficulty stems from the application (netperf) being run on much 
more than just a Linux system, so I cannot count on a Linux Filesystem Standard. 
 I was hoping there was a bit more of a "libxml2 filesystem standard"  which i 
suppose is why I was asking if the install of libxml2 - for example on HP-UX or 
Windows - should create /etc/xml

Again, I'm not looking to diverge, just trying to see how "invariant" /etc/xml 
happens to be.  When I install netperf, I will want to install its catalog, and 
to do that I will want to know where the master catalog is supposed to be, and 
if it is not there (eg /etc/xml/catalog) that it is "OK" for netperf's install 
to go ahead and create it.

I'm still a little fuzzy on why if libxml2 is expecting /etc/xml and libxml2 is 
ported to more than just Linux and so more than just the Linux Filesystem 
Standard, why it would rely on the OS to create /etc/xml, but if indeed, 
/etc/xml (where would that be under Windows?) is where libxml2 is going to look, 
and it would take a libxml2 source change for it to look elswhere rather than a 
configure option, I suppose I can consider /etc/xml an invariant.
