Hi, Bob.
When the specific.tml page is requested, Tapestry asks its components to
render themselves to generate the response. So, when <t:layout> on
specific.tml is asked to generate content, it knows that its body is "My
Page Specific Content". The content written by the component is:
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<head>
<title>My Tapestry Application</title>
</head>
<body>
<!-- my comment: t:body is replaced by the actual body -->
My Page Specific Content
</body>
</html>
So, you don't have to inject anything. The component knows what its body
is and know that it must be placed where <t:body> appears.
Atenciosamente,
Matheus Eduardo Machado Moreira
