Try replacing & with &
& is a reserved character and the XML parser is interpreting as the start of
an entity before it even reaches fop.

Subject: Can fo:external-graphic refer to image URLs? (fwd)
I notice that in all the examples I've seen, the src attribute of
fo:external-graphic points at a file. Can it refer to a URL? I wish to
generate PDF pages which contain lots of graphs. These graphs are
dynamically generated by a servlet which takes a URL containing the
data points in its query parameters, plots the graph on the spot, and
streams it back. So one of our URLs might look like
http://oursite/plotter/?points=1,2;3,4;5,6&caption=Growth&size=small
I've just tried this with FOP 0.20.1 and get back an error message:
Reference to entity "points" must end with the ';' delimiter. This
strongly suggests that it doesn't know how to parse URLs. (The URL is a
bit longer than the example above, and contains some escaped characters,
but it is valid and understood by both Netscape and IE.)
Of course, to be able to convert such dynamic URLs, FOP would need to make
an HTTP connection with the server and download the image, but that ought
to be possible. So if FOP can't handle images at the end of URLs, my
easiest bet might be to amend the source so it can - Java makes that easy
enough. Where in the source would I look?
