fo:external-graphic used with ps ?

[Drivet Grégoire]

Hi ,

I'm using FOP 0.94

Is it possible to use "fo:external-graphic"  with a postscript file as src ?
(e.g : <fo:external-graphic src="foo.ps"/> ). 
I made the test, it does not work but maybe I have to configure something...

Thx for your help

Greg
