If real pdf arrives at the browser, then xsl-fo rendering engine would
be invoked and complain that is wasn't seeing xml.

So you woould actually need to instruct the broweser to launch a
plugin that examined the first few bytes of content, to determine if
it was seeing xsl-fo or pdf, and routing the content stream to the
appropriate program.

Better would be to set the content type to a content type specific to xsl-fo.
