Re: [xml-dev] Compelling use case for XML Catalogs?

for example:
millions of xhtml files that start off

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

and similar variants.  If you access the dtd off the w3c server more 
than a couple of times your IP address will be automatically blocked and 
future requests will get an access denied http header.

If you don't want to edit every incoming file you need to redirect that 
request to a local copy of the dtd, catalogues provide one way of doing 

xhtml is just one example, same if you process docbook, or various 
microsoft project index files or any other format with a standardised 
location for dtd (or schema or whatever) you need to redirect requests 
from the standard location to your local copy of the resource.
