Oops - I lie. It wants the xml namespace imported, but it doesn't care
whether you have the xmlns attribute or not.
Cheers,

Wendy:
Oxygen is the same as Stylus.
Can somebody check it with Spy?

As noted earlier this was not in any 3.0 version. Further testing in
Stylus Studio shows 3.1 instance.xsd valid both with and without the line.
Also xml:lang is valid with or without this declaration.
I'm just testing things here. I leave it up to you to determine what is
correct.
