It which file do you define this macro?

It looks like you have been using the tal: prefix without declaring the 
right namespace.

from 'perldoc Petal':

<html xmlns:tal="http://purl.org/petal/1.0/">
   <body tal:content="bar">Dummy Content</body>
</html>

If you don't declare the Petal namespace, the prefix by default is 
petal:, not tal:

This will not work. Petal's implementation of METAL is only partial, and 
you need to read the docs :)
