title: How to print attributes of related objects in zope templates?
body: <p>I wrote an dexterity type with a field relating to another object:</p>
  
  <pre class="lang-python prettyprint-override"><code>institution = RelationChoice(
      title=_(u"Institution"),
      source=ObjPathSourceBinder(
          object_provides=IInstitution.__identifier__
      ),
  )
  </code></pre>
  
  <p>And also in the template I wrote:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;span id="institution" tal:content="context/institution" /&gt;
  </code></pre>
  
  <p>But it prints:</p>
  
  <pre><code>&lt;z3c.relationfield.relation.RelationValue object at 0xe3a032c&gt;
  </code></pre>
  
  <p>I have tried to get attributes to build a link to the item, but the next doesn't works:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;span id="institution" tal:content="context/institution/absolute_url" /&gt;
  </code></pre>
  
  <p>How can I get the attributes of the objecto to make a link to it?</p>
