TAL (Template Attribute Language) is a XML-attribute based templating language standard, used by Zope Page Templates, Chameleon and other templating libraries.
The language is aimed at making collaboration between designers and programmers easier, by hiding all templating constructs in XML or HTML attributes, allowing a template editor to create and maintain templates that still render in a browser.
