This figure shows a JESI `codeblock` tag scenario. In this example, the page consists of the following:

- A first block of template code that includes a `codeblock` tag that is set to specify execution of the code block only when a fragment is requested

- A fragment

- A second block of template code

The figure shows what happens in the situation where the fragment is requested. Everything is processed—all of the template, including the code block, and the fragment as well.
