rather pointless to continue using drm ! bcogney 06-18-2009, 12:15 PM Thanks Zelda for your comments. I agree with you on the DRM part, but it was just an option. For page-map, I meant page-map element referenced in OPF file, and I do have a page-map.xml file. Also, the checker complaints about width refernced in XHTML file? and suggestion on these items would be great. Also, if I want it to make changes to the XHTML file and rebuild it, what applications would you suggest using. zelda_pinwheel 06-18-2009, 12:19 PM Thanks Zelda for your comments.
