The Zope3 Template Attribute Languate (TAL) specifies the custom namespace and attributes which are used by the Zope Page Templates renderer to inject dynamic markup into a page. It also includes the Macro Expansion for TAL (METAL) macro language used in page assembly.

The dynamic values themselves are specified using a companion language, TALES (see the zope.tales package for more).

The reference documentation for the TAL language is available at https://pagetemplates.readthedocs.io/en/latest/tal.html

Detailed documentation for this implementation and its API is available at https://zopetal.readthedocs.io/
