Shouldn't it be possible to declare a standard "icon" in the svg spec to be
used for missing references? As of now, Renesis v3 will show an explicit
marker (defined as SVG;) when something is missing whereas other
implementations (most of them) do actually behave as if there've been no
fill / stroke for example, not sure what they do for images (Erik?). This
might lead the author to be pretty much confused at the very end about
what's going though as I am not sure whether he might really be able to
automatically know that a no-fill / no-stroke might mean an
invalid-reference thingy? Just my $0.02
