[Zope] how detect a variable from template father?

[Miguel Beltran R.]

Hi list

I have 2 templates, in second template I need render a <span> only when the
first template have defined a variable.

template1:
<ul tal:define="var1 python:1">
   <li tal:replace="structure conext/template2"></li>
   <li tal:replace="structure python:conext.template2(var2=1)"></li>
</ul>

template2:
<li>
   <input id="x" name="x" value="somevalue">
   <span tal:condition="exists: var1">span2</span>
   <span tal:condition="exists: attr/var1">span2</span>
   <span tal:condition="exists: context/var1">span2</span>
   <span tal:condition="exists: container/var1">span2</span>
   <span tal:condition="exists: options/var2">span3</span>
</li>

any condition in span not work :(
