Doitsu said the same thing. Under epub "2.0" spec of 2007, you need the opf namespace to use the file-as, scheme, and role attributes as they are not part of the dc namespace nor allowed for those metadata elements. So what is here should be technically correct.
Doitsu pointed out that under epub "2.0.1" spec in 2010 file-as, scheme, and role have been added as allowed attributes for the dc: namespace metadata tags. He said that epubcheck uses the "2.0.1" spec which means they do not need the attribute namespace additions (none of them).
Once I get back I will look at this, and if this is incorrect, we can release a quick Sigil-0.9.5 to fix this, the wcc validator, and the bug in importing HTML metadata
