Possible Bug in display of group with xxforms:internal option

When you mark a group's appearance as xxforms:internal, and the group is
not relevant, the contents of the group are still rendered. I'm not
sure if this was by design or not.

see this text</xforms:group>

Jeremy,

The appearance="xxforms:internal" indicates that the xforms:group is
not "materialized" in the generated HTML, i.e. no element in generated
for that xforms:group. So you can't use it on a group which sometimes
needs to be hidden, as hiding the group is done by adding a class on
the HTML element corresponding to the xforms:group, which in this case
doesn't exist since you asked for no element to be generated.

The appearance="xxforms:internal" is often used when you want to put
an event listener around a number of controls. In that case you need a
xforms:group around those controls, but also having an HTML produced
in the page would be a waste as it isn't necessary in that case.
