Correct me if I'm wrong, but after thinking about it, I deducted that the
"or" in a tales-statement:
<td tal:content="item/title | default">No Title</td>
doesn't work like the "or" of python:
<td tal:content="python: item.title or default">
because for python the empty string is false while the tales-statement
returns true if the variable exist without caring about its value. I think
this should be fixed because the second solution adds unnecesary complexity
to the tal-expression and I also think that it's an inconsistency that one
works and the other don't.
