Is there a current() function in XForms?

Hello,
I've searched all over for this, and found nothing
so I'd thought I'd ask here.
Is there any equivalent of the XSLT current()
function in XForms for use in a repeat structure?

Example of what I'm trying to do in XForms,
using current() as if it were in XSLT:

<xforms:instance id="main">
   <instance>
     <something ref="1"/>
   </instance>
</xforms:instance>

<xforms:instance id="lookup">
   <instance>
     <anotherthing id="1">One</anotherthing>
   </instance>
</xforms:instance>

<xforms:repeat nodeset="instance('main')/something">
   <xforms:group ref="instance('lookup')/anotherthing[@id=current()/@ref]">
     <xforms:output ref="."/>
   </xforms:group>
</xforms>

or does anyone knows how I can lookup stuff from within a
repeat structure?

Cheers
- Mark Gibson

Oh bugger, I've done it again, RTFM, just found:
xxforms:repeat-current()

How I overlooked this I don't know!!!
Sorry.

Mark,

Yes, you found the right function ;-)

As mentioned earlier, the current XForms 1.1 proposes a current()
function that has nothing to do with xforms:repeat, but that returns the
XPath context of the XPath expression. Once this is implemented, you
won't need to use xxforms:repeat-current() in your use-case.

We have a bug entry to track this new feature:
