This often takes a bit more work, a nice example of this is Django-tagging... .
You could also create each app so it's totally independent .

What Alex Reitbort tells.
This will guarantee that xml serializer will be able to deserialize old xml into new object, and that object will have "sane" values .

I once built a very good web application in ASP (classic) back in 2001 and extensively used XmlHttpRequest object in it. (I was lucky that the clients were only using IE, and only IE supported this object at that time ).

In the 10 years I've been programming, I can count the number of data structures I've used on one hand: arrays, linked lists (I'm lumping stacks and queues in with this), and dictionaries. This isn't really surprising given that nearly all of the applications...

Some maps are unordered maps/sets): skip lists give you built-in constant time iteration from one element to the next graphics.
