I didn't make that part as clear as I thought. The epub file I was using for these checks has been clean on Epubcheck for years until I tried interfering with the quotes. Each type of interference I tried, and I only tried a single instance at any one time, caused Epubcheck to flag a load of "Fragment identifier not defined" errors in multiple chapters.
The fragments I looked at were all footnote links in the text body linking to a reference at the end of the chapter. Only one footnote/chapter. The footnote had a return link to the text. These fragments had all worked fine for years and had never been flagged as undefined by Epubcheck over multiple checks.
As soon as the quotes error was corrected, the next Epubcheck was completely clean with no reference to any fragments in any chapter.
I haven't understood the possible connections between a single missing or mismatched quote and unidentified fragments elsewhere. It seems a most unlikely scenario.
