Just think of XSL as a vocabulary you can use to create nice PDFs.

In theory, you can use XSL in a browser...

The nice thing about XSL is that you can:

• Use XSLT to re-arrange the output.

• Specify page sequences for different page layouts.

• Control the page layout (body, headers, footers, etc.).

• There is an expression language that lets you calculate expressions against the rendered tree.
