Someones you really want a text based processor, for example when
creating emails, CSS or javascript. Of course you can do that using a
XMl based templating system but the result is very hard to read or edit .

One reason I really like genshi is that it can do both: it enforces
valid XML (although you can opt for html) using an attribute style
syntax similar to TAL but you can also use it using a substitution-style
syntax (in which case it will still enforce valid XML!). This is very
practical when producing xhtml where you need to insert a bit of
javascript. Being able to do something like this is right in your html
file is extremely practical:

    <script type="text/javascript">
/* <![CDATA[ */
        var rateChangedHandler = function (oArgs) {
            var record = oArgs.editor.record.getData();
            var postData = "rate=" + oArgs.newData;
            YAHOO.util.Connect.asyncRequest("POST",
                    "${h.url_for(controller='currency')}/" + record.code + "/update",
                    null, postData);
        };

/* ]]> */
    </script>
