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

1. 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
2. A fragment
3. 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.
