 I do not think one needs to be an existencialist here ;-)

 In similar cases I try something like:

<select>
  <option selected 
     tal:repeat="record loop"
     tal:content="record/title" 
     tal:attributes="
        value record/id;
        selected python:test(is_current_record, default, nothing)" />
</select>

 If an attribute in the tal:attributes clause is set to "nothing";
it will not be rendered.

 Using "default" for the "select" attributes renders the tag as

  <option selected="selected' ...

 I guess this is something that You may want. Only rendering 
'<option selected ...' seems not to be supported, as it is no valid
XHTML, but even Netscape4 seems to understand the '<option select="selected"'
notation.
