Linking from PDF to external http-urls?

[Johannes Fiala]

hi there,

am I right in that embedding links to external URLs is not yet supported with FOP?
I tried these examples, but non of them opened up the URL as specified (although no warning has been printed during rendering):

 <fo:basic-link external-destination="http://www.yahoo.com" text-decoration="underline" color="blue">
 yahoo.com </fo:basic-link>

 <fo:basic-link external-destination="url('http://www.RenderX.com/')"
               text-decoration="underline"
               color="blue">RenderX Home</fo:basic-link>

I hope anybody can shed more light onto this...
