XML allows you to generate complex, structured, hierarchical data that 
can be read, changed, and stored by well-tested third party libraries 
that don't need to know anything about the contents or meaning of your 
configuration data beforehand.  This means I, as a developer, don't need 
to write any code to read and parse configurations, validate the syntax 
or structure (only the content), or persist it back out.

In simpler terms: less time spent on the configuration parser, more time 
spent being productive.

If there was a less-verbose alternative that was as easy to implement, 
with known stable parsing libraries, that had the same expressiveness as 
XML, I'd probably use that instead.  But when you're talking about data 
that goes beyond a simple list of name/value pairs, anything attempt to 
stream it to a flat-file format is going to result in something that is 
either 1) redundant, or 2) hard to read.  I'd go with 2 over 1 any day.

In my opinion, if the worst thing you can come up with to complain about 
is "they used XML for their configuration files", then I'd say that 
software is in pretty good shape.  On the other hand, even I can see 
that HAL has plenty of problems (besides its XML configuration).  The 
fact that it completely fails to work for you being a good example :)
