license and patent issues with PMXML

Hello!

I'm involved in development of the KPlato (K PLanning TOol, 
http://www.koffice.org/kplato) application. Currently we use our own 
(XML) format for storing documents. As KPlato has not yet been 
released changing the format is not affecting users.

We consider PMXML as an option. We have a few questions though:

1) What is the license of the PMXML format? Can it be freely used by 
open source projects like KPlato?

2) Are there any patents we need to be aware of when using the format?

3) How far is the standardization process?

You can also answer directly to the [email protected] mailing list.

Thanks a lot!
