I checked the archives and came across a thread from a few months ago that touches on what I want to do.  I have an optional element, but I want to limit how many times it can repeat.  Let's say, for example, no more than two times.  Here is the thread: http://www.nabble.com/control-the-numbers-of-a-repeated-component-in-a-node-td23313475.html#a23494458 .  Here is another good source on binding/relevant: http://en.wikibooks.org/wiki/XForms/Relevant

I'm having problems putting it into practice.  I have it almost working, but I must be missing something.  Here is a bit of code:

<xforms:bind nodeset="editionstmt" relevant="count(//editionstmt) &lt; 3"/>

<xforms:trigger appearance="minimal" ref="editionstmt">
  <xforms:label>
    <img src="../apps/editor/images/add.gif"/>Add Edition Statement</xforms:label>
    <xforms:insert ev:event="DOMActivate" context="." origin="instance('editionstmt-template')" nodeset="."/>
</xforms:trigger>

<xforms:repeat nodeset="editionstmt">
   <div>
    <xforms:input ref="edition">
      <xforms:label>Edition</xforms:label>
    </xforms:input>
  </div>
</xforms:repeat>

This example disables the trigger only after it has been clicked to add a third item.  Not only does the trigger disappear, but the two existing inputs also disappear.  My guess is that I have constructed the relevant attribute incorrectly.  Does anyone know a better way of doing this?

Thanks,
Ethan Gruber
