Susan,

I was, but now you're taking people in the wrong one ;-)

It wasn't evident because it isn't true. You are mixing up two things - the
UI and the model. All descendants of 'page[1]' in the instance data would
indeed be disabled if 'page[1]' was disabled (provided that they themselves
didn't have a @relevant rule that overrode this), and that is what the spec
means when it says that @relevant is inheritable. But that has nothing to do
with the descendants of xf:group.

You can only affect the descendents of xf:group with CSS - which is what my
example was showing. You wrote:

but the reason the xf:output gets hidden is because the CSS style on
xf:group is automatically set to 'display: none;' when the node that the
xf:group is bound to becomes disabled - as determined by the rule in the
@relevant model item property. This means that any markup inside the
xf:group will be hidden, but we need to be clear that this is thanks to CSS,
and not the XForms model.
