Adam,

Sorry to be the bearer of bad news, but XForms 1 doesn't support XPath 2,
and the xf:case element doesn't have a condition attribute.

Ideally you should be able to do what you want simply via the @readonly MIP
in combination with CSS. However, it will depend on which processor you are
using as to how close you will get to your ideal in terms of the actual
appearance.

For example, with formsPlayer, when an input is readonly you can still edit
the contents of the control, but the change won't be committed when you
navigate away from the control--which is at least the correct behaviour,
even if it doesn't look great. (Basically, it's because readonly is
processed in the model not the view, but it's on our list of things to
improve :)

Other processors may completely lock down the control when it's readonly, in
which case it will 'feel' more like an xf:output. So if you can use the
:readonly pseudo-class to style the control so that it doesn't look like an
xf:input, then you've got pretty much what you want (without having to use
lots of switches and cases).

Regards,

Mark
