I created an epub with calibre. Epubcheck 4.2.2 finds the following warning:

Code:

WARNING (OPF-085): /tmp/tmpcLvCwX/temp.epub/content.opf(14.106): 'dc:identifier' value 'uNEzNk4WVhyXJvFBinoWjG5' is marked as a UUID, but is an invalid UUID.

The warning refers to the following line contained in the "content.opf" file

Code:

<dc:identifier id="uNEzNk4WVhyXJvFBinoWjG5" opf:scheme="uuid">uNEzNk4WVhyXJvFBinoWjG5</ dc:identifier>

Can it be a problem for the epub quality? How do I solve the problem?
