Value is normally set to an API call to retrieve an object such as a Page, Post or Contact.
<logic:variable value="[? \Components\Website\Pages::current() ?]" as="page" />
After setting variable $page, render the page title as a heading:
<h1>[? $page['page_title'] ?]</h1>
Hint: View the data stored in a variable with in-line PHP:
[? varDump($page) ?]
