6.3 Custom Tag API

The Custom Tag API is a way for programmers to provide access to Python objects to HTML designers in their templates without having to know any Python code. The down side of this is that you will be introducing your own set of non-standard HTML tags into the markup, making it a little more difficult for transitioning projects to people who don't know what all your tags mean. On the other hand, it can be a very powerful tool to enable HTML designers to completely prototype an application without requiring Python code modules.
