Re: [Xsltforms-support] Cross instance XPath evaluation

Hello William,
It is very important to add xmlns="" at your instances because latest
releases of FireFox are capitalizing attribute names when in the xhtml
namespace.
I clearly see a difference with this and it seems OK for me now.
Can you please confirm?
Thanks!
