If $mediaobject-output-paths is true, media object locations are assumed to be correct, relative to the resource base URI. For example, if the fileref is path/to/image.svg, that relative path will be preserved as the relative location against the resource base URI in the output.

If this parameter is false, then the path component of media objects is discarded. All media objects are assumed to be in the location identified by the resource base URI. In other words, path/to/image.svg will be treated as if it was simply image.svg.
