I just don't see how using XML internally in an app is extra work compared
to using individual attributes or another structure format. And I don't
understand where there is any appreciable overhead. Of course, my ignorance
could very well be bliss!
Advantages that I see:
1. Data for a particular object is "bundled" nicely together in a
way that is very readable
2. I can easily maintain before and after pictures of an object at
the client and do not have to create session variables to do so. This way I
can also maintain cart info across expired sessions without loading the
client up with cookies or saving User data
3. Now that I've found out that I can validate against the schema,
I don't have to maintain basic validation rules at both the UI and Business
Object level. Question that I am working through is how to translate
xmlValidate error responses to user friendly messages at the UI layer
4. I can create an object once and easily include in other
objects(e.g. Address in an Invoice). Of course I could also do this using
includes...
5. I can create XML test files and quickly and easily run
regression test on all code
6. I am starting to like the way using xmlSpy to create schemas and
xml helps me think through how I am organizing, validating and representing
objects

What exactly are these advantages?
