Maybe my brain is in worse condition than usual. But, I'm not really sure what you've tried here. In my experience, if you've given Batik a URL as the document there's no need to set xml:base. The document already has a base URL and all references are relative to that URL. Normally the xml:base and such are needed if you create the SVG on the fly. > BTW, for my purpose the best solution would be addition of new > transcoding hint which would be set on the fly - no processing DOM or > placing xml:base attribute into SVG document.

I can't see the use of a proprietary approach for something this common. Unless, I'm really missing the point. G.
