Limiting repeats

Ethan,

Try wrapping an xforms:group statement around your xforms:trigger element,
like so:

<xforms:group ref=".[count(//editionstmt) &lt; 3]">
<xforms:trigger appearance="minimal">
 <xforms:label>

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

</xforms:group>

This will cause the trigger to disappear when the count of editionstmt hits
3, but it shouldn't affect anything within your xforms:repeat.

In addition, if you provide a reproducible sandbox example I could try and
give you more insight as to why your previous code wasn't working as you
expected it to.
