Hi,

data uri is a good idea.

About the resource resolver, I am instantiating my FopFactory from a
config file:

FopConfParser confParser = new FopConfParser(fopConfigFile);
fopFactory = confParser.getFopFactoryBuilder().build();

So there's no way to pass a resolver. Perhaps I can put it right into
the config file?
