The idea in a template system is, the model provides the data and the
template interpolates it.  So in this case, the template engine takes
the template
            <li node="rep:item">
                <a href="" node="con:link">LINK</a>

and a Python list and combines them to give
                <a href="index.html">Home</a>
                <a href="products/index.html">Products</a>
                <a href="about.html">About</a>

No manual concatenation is involved.

The callback organization is interesting but seems more cumbersome than
the more-traditional approach you see in Cheetah et al.  I guess if you
are absolutely allergic to any sort of code whatsoever in your
presentation layer, though, HTMLTemplate might be the way to go. :)
