(please forgive me for cross-posting -- I'm not entirely sure where this message should go)

Hello! I'd love to create (or find, though I don't think one exists) a browser-based word processor that uses XML as the native code for its documents. This would enable true platform-independence. Does anyone out there have any guidance as to how I could get started?

Any info you can share is most welcome...

Thanks in advance,
Dieter
