Yes, if you embed the SVG in the XML document: use configuration element documentResources (http://www.xmlmind.com/xmleditor/_distrib/doc/configure/documentResources.html). No, if you just reference an external SVG file. > and copy them into the temporary working directory with all other > resources before running the actual XSL conversion ? > We used to support references to SVG graphics themselves referencing external files in v3 (including in File|Save As) and we definitely removed this feature because its implementation was much too complicated given its usefulness. You need to use an SVG editor which allows you to embed external files in the SVG by the means of a "data:" URI (http://www.ietf.org/rfc/rfc2397.txt). Actual example (excerpt of a SVG file generated by Inkscape): --- <image xlink:href="data:image/png;base64,iVBOR ... mjBbbCcAAAA AElFTkSuQmCC " x="60.840504" y="62.153378" width="127" height="28" id="image2591" /> --- FOP, Batik, XEP all support "data:" URI. (Very) Recent versions of Inkscape (http://www.inkscape.org/) allow to do this simply by using an option (Effects|Images|Embed All Images -- http://tavmjong.free.fr/INKSCAPE/MANUAL/html/Effects-Images.html#Effects-EmbedAllImages). We use this Inkscape feature for our own needs.
