First a hello to the group, I've been a subscriber for a while, but this is
my first question/contribution to the list.

I'm very familiar with CF, and I have a conceptual understanding of XML.
However, I have trouble finding a real-world usage of XML with the apps that
I build. I know I'd love to use it, I just don't know how. It seems in every
example I've seen (which are few and mainly add to the concept, I admit)
I've not run across anything that would set off a lightbulb in my head to
say "I could use that" - how to make a CD catalog or Simple Inventory is
fine, but why would I use XML versus a database? I realize the meta-data
markup to a document is extremely valuable, but I've seen no metrics on
performance, or how that meta-data could be leveraged with something more
complex than a simple catalog.

So with that said, does anyone out there have real-world apps built on a
CF-XML architecture they would care to explain, even if just an brief
overview? The technology needs no explanation, just how it's being used.

I apologize if that's a vague question, I'm just having trouble grasping the
flow of data
For example:
- user input(form) to xml then to end-user.
- user input(form) to a database field as XML, then queried and transformed
via XSL to the end user
- database fields queried, written to XML then transformed via XSL to end
user
- database fields queried, written nightly to XML documents, then syndicated
across HTTP streams to subscribers

Some/None/All of the above? I can't seem to find a "best practices" for
leveraging XML in dynamic apps.

Any help appreciated, even if it's links and/or a reiteration of an existing
email that was similar to my question.

Thanks!

Brandon Wolf
