The XForms 1.1 spec says:
a).
6.1.4 The relevant Property
Description: indicates whether the model item is currently
relevant. Instance data nodes with this property evaluating to false
are not serialized for submission.
This seems to ignore the relevant="false"
attribute of submission.
b)
11.2 The
xforms-submit Event
...
2. If the binding attributes of submission
indicate an empty nodeset or a non-element node, then submission
processing is stopped after dispatching event xforms-submit-error
with context information containing an error-type
of no-data. Otherwise,
the binding attributes of submission
indicate a node of instance data.
This seem to contradict the default
value of the ref attribute of submission being "/".
