Yes, you will need to use that when your graphic element
is set up with an ENTITY attribute which is how yours is.

Right, your DTD is set up to use the ENTITY method for referencing
graphics, not the file path method, so Epic is acting accordingly.

Now the XSL you'll write to generate HTML or FO's will have to
make use of unparsed-entity-uri() to get the path and pass it
on to the img or fo:external-graphic element being generated.
