Apart from being illegal XML (look closely), the code above is likely
to fail due to additional whitespace in the value of the src attribute,
It will generate something like src="%0D%20%07...http://...".

The following corrects this and also uses an alternative code style 
(literal elements and attribute value templates) in order to gain
some readability:
  <fo:external-graphic
    src="http://workstation/cocoon/development/_images/{location}"
    height="100px"
    width="100px"/>

Note also this requires a HTTP server running on host "workstation"
which is able to serve the graphic. If you want to read directly
from the file system, use the file: protocol
  src="file://cocoon/development/_images/{location}"
(If this gives errors, try file:/cocoon... or file:///cocoon...,
implementations vary may a bit).

Another point is that measurements should not be given in pixels (px)
in most contexts, you should try millimeters (mm), points (pt) or
something like this first. Pixels are not well defined for PDF output.
