Write a mortgage calculator as explained (and prototyped) at:
http://people.cs.uchicago.edu/~asiegel/courses/ace104/lesson1/examples/mortgage
The application must take the specified data as input (length of
mortgage, interest rate, etc.) and return a reasonably formatted
amortization table. The only constraint on the program is that XML be
used at the "middle layer". That is, your program must take input
data, do computation, return structured XML data, and that XML data
must be further processed to produce a columnar output. I'm flexible
as to exactly how you implement this as long as above constrations are
met.

For example, two options are:

 - web-based code analogous to prototpe. Input via form data, output as XML formatted using
   css, XSLT (this would be getting ahead), or by hand-rolling html from XML
   from within your program.

 - stand-alone app. You can use command line or gui input, spit XML out to file and have
   a second app convert XML to formatted columnar output. In between you'll have to validate
   XML. At minimum do so by hand, but try to be a little slicker and include in your program
   if you can.

Any language is fine. Main goal is to understand how XML can be used
to de-couple display from data content, mechanics of mapping internal
data structures to XML, etc. Main details are left up to you.

Please let me know asap what your language(s)/strategy will be so I
can prepare what I need to grade.
