Sorry for the delay in responding to this problem. I'm fixing bugs now, but I am unable to duplicate your problem. When I run your make process on your files, the resulting epub passes epubcheck. Your zip file did not include your OEBPS directory, so I could not compare my output to yours. Also, did you use a catalog file to map the XSL to a local directory, and which version of the stylesheets was that?
