Actually, it does....  I just don't know if that ever got exposed to the 
public or not.  (Of course, the customers that wanted XML-based configs 
also wanted ION, so it might only have been exposed on ION.)

While I was there (2000-2005) there was a big effort to have all config 
files be represented as XML.

If you ever tried to "diff" two configs of a 7216 (VXR/CMTS) that were 
from different releases, you'd know why.

This would drive customers crazy: portions of config would move around, 
whitespace would appear where it wasn't previously, names of commands 
would gratuitously change, etc.

Parse-trees would be easier to diff.

There were some interesting efforts floating around to have the 
configuration be sucked up via XML/secure-RPC to a client, edited there, 
and then pushed back into the router/IAD/firewall, what-have-you.

The IOS parser was one of the hairiest pieces of code I had ever had to 
maintain.

But we're getting off the subject.
