Patent on XML and XSLT together?

This was claimed as something Sun is trying to do:

Basically if you chose a stylesheet to transform your xml based on browser
type or some (any?) other criteria, you'd be in violation of this patent if
it becomes one. Originally seen on the axkit.org "daily churn".
