On another note, I think that tal:define="" is the ugliest part of zpt.

If only it was possible to define which attributes could be set by a tal 
expression, and then put the tal into the attribute itself, I would be 

So instead if this:

<a href="#"
    tal:attributes="href here/absolute_url;
                    title here/title;
                    id here/getId"

I could write this:

<a href="here/absolute_url" id="here/getId" title="here/Title"
    tal:attributes="href; id; title"

All that would be needed for this syntax, is if an attribute in 
tal:attributes didn't have a definition, it would look in the attribute 
itself for the tal.
