Tapestry elements are elements defined using the Tapestry namespace prefix (usually "t:").
All other elements should be in the default namespace, with no prefix.
There are a certain number of Tapestry elements, listed below, that act as template directives; beyond that, any element in the Tapestry namespace will be a Tapestry component.

In many cases, a component is designed to integrate have its template with its container's templateintegrate with, or "wrap around", the containing component.
The <t:body> element is used to identify where, within a component's template, its body (from the container's template) is to be rendered.

The following example is a Layout component, that adds basic HTML elements around the page-specific content:
| Code Block | ||||

<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd">
<head>
<title>My Tapestry Application</title>
</head>
<body>
<t:body/>
</body>
</html>
|
That "<t:body/>" element marks where the containing page's content will be inserted. A page would then use this component as follow:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<t:layout<html t:type="layout" xmlns:t="http://tapestry.apache.org/schema/tapestry_5_3.xsd"> My Page Specific Content </t:layout> | ||||
| Info | ||||
In this example, t:layout creates a Layout component (more on this shortly).html>

When the page renders, the page's template and the Layout component's template are merged together:
