using xforms:repeat with binds instead of nodeset/ref

OPS seems to have a problem when I specify a bind on a repeat and binds
on the child repeating controls, instead of a nodeset on the repeat and
refs on the child repeating controls. I get the correct number of
repeats, but it's just the first item repeated n times.

eg

<data>
<item>
<value>apple</value>
</item>
<item>
<value>orange</value>
</item>
<item>
<value>pear</value>
</item>
</data>

<xforms:bind id="items" nodeset="data/item">
<xforms:bind id="value" nodeset="value"/>
</xforms:bind>

<xforms:repeat bind="items">
<xforms:input bind="value" .../>
</xforms:repeat>

So here I'd get apple+apple+apple instead of apple+orange+pear. Changing
the repeat and the child controls to refer to the data directly using
nodeset + ref corrects the problem.

I assume this is valid markup since it worked ok under Chiba.. ?

Attached is an example demonstrating the problem.

Adrian,

The behavior of binding to an inner bind id (in your case, the "value"
bind) is not clearly specified by the spec. This issue is currently
discussed within the XForms Working Group.

Some engines apply the "first node rule" (i.e. your bind returns always
the first <value> element). Some try to look at the current repeat
iteration to make a choice (which is clearly not specified by the spec).
OPS does the former.

The bottom line is that currently, you should not do that unless the
outer bind returns only one element, and use nodeset / ref instead.
