the same concerns are for other types of config files, and at least if you
use XML you have various standard tools that are better tested than special
purpose parser you would have to write for other type of file.
even if standard parser blows up the worst situation is that you would
have to fix it or write your own parser. so the worst case scenario in case
of using XML is the bext case scenario when using some proprietary config
file...
and using XML has added advantages of e.g. being able to present config
data to users using style sheets etc...

I use SGML/XML for documentation. But I'm not entirely convinced
that XML is appropriate for config files.
My experience has been that existing XML parsers blow up when
they
have to deal with large files (like a 700 page users manual). I'm
worried
about what would happen if they had to parse a large config file similar
in size to a sendmail.cf.
What happens if the bottom of a large config file gets chopped
off? Will existing XML parsers still parse an invalid XML file? What if
someone manually edits a file and makes it invalid?
