Ah, yes, I know all about this, and didn't think of it at the time.   
Sorry :-)

I've discussed this with the maintainer of libxml2 and mailed him a  
patch for his consideration a few weeks ago, but unfortunately he  
hasn't gotten back to me about it yet.  I've now put a ticket on Trac  
so that others can see it [1]; I've only recommended the  
substitutions in some of the places that "/etc" appears because the  
other instances appear in documentation that seems less system- 
specific.  My impression from the libxslt code was that it inherited  
the default catalog location from whatever was compiled into the  
libxml2 code, but that there are hardcoded references in its  
documentation (including the printf in xsltproc.c) that ought to be  

I think you're absolutely right, however, that this is an issue that  
ought to be reported upstream.  If you could do that (possibly  
improving on my patches), that would be great.

Kind regards,
