I agree.  That was a bad idea.

I don't think a general need has been demonstrated.  This is the first 
case I can recall seeing.

I do think that this case should be fixed, one way or another, in 
/etc/postinstall/fontconfig_dtd.sh.  That script assumes, on the basis 
of [ -x /usr/bin/xmlcatalog ], that the catalog /etc/xml/catalog has 
already been created.
