DOCBOOK-APPS: Vector graphics within PDFs ?

Hi,

I was wondering whether vector graphics formats could be used within
PDFs ?

Currently, we use a Mandrake distribution, 7.2, updated with the following

packages:

docbook-dtd41-sgml-1.0

docbook-style-dsssl-1.72

jadetex-3.11

openjade-1.3

I tried EPS files, but I get complaints from the tex (variant). Of course,

JPG and PNG work fine, but these are raster formats...

Any idea ?

    Regards. Thomas.
