I make extensive use of SVG images in my xsl:fo using the
instream-foreign-object element (see example below).  What I'd like to be able
to intercept the calls that RenderX makes when trying to source the images
(xlink:href) and rather than going to the file system or the local web server
(if we specify xml:base as http://localhost/) I would like to retrieve the
images from a database.  I have had a look into URIResolver and EntityResolver
but neither of these go down to the required level.

Is there anyway that I can do this with RenderX?  Either using a java library or
chaging my xsl so that the URIResolver/EntityResolver are called whenever an
image is requested?
