While making TextIndexNG3 compatible with Zope 2.10 I encountered the following bug with a view registered through Five: 

 ['Compilation failed', "zope.tal.taldefs.TALError: Path element may not be empty in 'context//@@words_vocabulary' in expression 'nocall: context//@@words_vocabulary', at line 33, column 3"]

The related ZPT code looks like this:

<tal:if condition="request/pattern|nothing" >
  <div tal:define="wv nocall: context//@@words_vocabulary;
                   words python: wv(request.get('pattern'), request.get('language'))">
    <ul>
      <li tal:repeat="word words">
        <a tal:attributes="href string:documentsforword?word=$word" tal:content="word" />
      </li>
    </ul>
    <span tal:condition="not: words">No matching words found</span>
  </div>
</tal:if>
