ePub Error: [ERROR]OEBPS/Text/index_split_000.html: 5,56: value of attribute "xml:lang" is invalid; must be an RFC 3066 language identifier

Hello:

I keep getting the same error (18) times when loading my ePub. This ePub passed Smashwords - probably because their meatgrinder corrected the error, but I still need to fix it to load it on other sites.

[ERROR]OEBPS/Text/index_split_000.html: 5,56: value of attribute "xml:lang" is invalid; must be an RFC 3066 language identifier

The "split" section of this error goes from 000 to 018, but everything else is the same.

Can anyone provide an answer what this error means?

Thank you!
