Documents are generated by facelets documents using tags in the http://jboss.com/products/seam/pdf namespace. Documents should always have the document tag at the root of the document. The document tag prepares Seam to generate a document into the DocumentStore and renders an HTML redirect to that stored content. The following is a a small PDF document consisting only a single line of text:

<p:document xmlns:p="http://jboss.com/products/seam/pdf">                                                      
   The document goes here.                                                                                             
</p:document>
