OK I will change that.

Those are the flag fields in the current SLF nodelist.

 CC> XML Schema, most definately!

From what I understand this is the best way to go. We will need some experts
to help us develop a good schema (nudge, nudge)

Yes, yes and yes

OK.

And because of this I think the best way to go is child for almost if not
everything.
