I have just loaded this plugin to check an epub2 file because I haven't been able to get any response from http://validator.idpf.org/ - every attempt over the past few days has just timed out without any connection to the server. Is the online checker still in business?

The check with this plugin worked fine with 'No problems found'. Then I tried setting 'usage' to true and this produced a few errors (or suggestions) such as :

USAGE(HTM-021): Content file doesn’t contain lang attribute.
Col: 151: USAGE(ACC-013): Content file contains at least one inline style declaration.

Can you point me to a reference where I can find the key to stuff like ACC-013 and HTM-021 ?
