What are the possibilities with LOTRO's XML?

[SlopranoDark]

Hello everyone

After many years of absence, I decided to revamp my good ol' plugin.

I've grown up and I'm at college learning among other things XML.
I just got taught it's basically the same as JSON and CSV.

So I'm wondering, assuming things in LOTRO's XML have been pre-defined, what can I edit and what not?

For example; Would I be able to implement animated images? What 'records' or 'tags' are available? Is it possible to convert the XML being used to JSON or CSV? Etc.

If anybody knows, please reply here!
