Can't decipher remaining EPUB validation errors
Hello. I have four errors remaining from my ePUBChecker report, and I'm at a loss to figure what they are, although I think they relate to EPUB 3 instead of EPUB 2.
Here are the errors:
ERROR: /Users/shawngirsberger/Documents/MM/EBOOKS/Hanna/working/hanna_book3.epub/OEBPS/content.opf(2): bad value for attribute "version"
ERROR: /Users/shawngirsberger/Documents/MM/EBOOKS/Hanna/working/hanna_book3.epub/OEBPS/content.opf(59): attribute "properties" not allowed at this point; ignored
ERROR: /Users/shawngirsberger/Documents/MM/EBOOKS/Hanna/working/hanna_book3.epub/OEBPS/toc.xhtml(8): unknown element "nav" from namespace "http://www.w3.org/1999/xhtml"
ERROR: /Users/shawngirsberger/Documents/MM/EBOOKS/Hanna/working/hanna_book3.epub/OEBPS/toc.xhtml(126): unfinished element
I've attached the guilty files. This was originally a print book laid out in InDesign CS6, which was exported as EPUB 3 -- hence the toc.xhtml file, which doesn't seem to be part of EPUBs generated from ID CS5.5/EPUB 2.
The book looks and functions just fine on an iPad and a NOOK color, but of course, these errors have to be cleared up before I can send this to the distributor. Sigh.
Your advice is greatly appreciated. I hope I will be able to contribute something here some day.
P.S. I will probably deal with the %20 in the file names of the images that have them. I never put spaces in file names any more, but there were in the author's files, and I didn't change them before starting the project. Thanks to some of the posts here, I'll be more diligent about checking for these.
