TAL

template attribute language discription from “wikipedia”.
The Template Attribute Language (TAL) is a templating language used to generate dynamic HTML and XML pages.
Its main goal is to simplify the collaboration between programmers and designers.
This is achieved by embedding TAL statements inside valid HTML (or XML) tags which can then be worked on using common design tools.
TAL was created for Zope but is used in other Python-based projects as well.
