That is interesting. Is there backup for this in the spec today, e.g.
should an implementation do this today?

This is actually how formsPlayer works; everything that could take a
binding attribute (@model/@ref/@nodeset/@bind) will use the current
context if none is present.

So this:

    <bind readonly="true()" />

would set the root node of the first instance in the current model to
read only.

As a result of this, I have often thought we should drop the fact that
submission/@ref explicitly defaults to "/", since that is already
implied by these same rules for context. The following would still use
the root node of the first instance, even if we removed this explicit

      <submission action="http://..." method="post" />

Of course, much more controversial would be to continue the
and allow @ref to be optional on form controls!:

        <label ref="." /
