I'm sorry, I didn't mean to block a release. Instead, I tried to find spots
where I could help, even with my lack of understanding of the xsl-fo internals.

I do agree that the current handling of the src attribute in external graphic
already covers the majority of all cases, thus greatly enhancing the functionality
of xmlroff.

What do you imagine to happen ? Drop in a fallback graphic ? Do nothing in
the generated document but print out a warning / error ?

What is the expected behavior ? To stretch / shrink the image to fit ?

I may look into that.
