[a-name4epub]

I'm looking for advice on a couple of errors I'm seeing. One is " exists in the zip file, but is not declared in the OPF file" but the files in question Are declared and I've checked, rechecked, and even renamed some files in both the opf and nxc files and still they show up as errors. Similar errors for (mostly) the same files is "referenced resource exists, but not declared in the OPF file" - how does this happen?

Another is "hyperlink to resource outside spine" but these are links to files within the epub. I read elsewhere on this forum that "id" works as links within the epub. I tried that and got "elements must consist of well-formed character data or markup." Is something more needed? I put /> where normally there would be </a>.

One file gives me "text not allowed here" but it is xhtml the same as all the others (this is an epub with many xhtml files).

Thanks for any assistance with this. I thought I had it figured out before epubcheck!
