opf:meta... change not accepted by Sigil

[Doitsu]

With the following metadata section I'm getting the following error:

ERROR(RSC-005): Error while parsing file: Property "role" must refine a "creator", "contributor", or "publisher" property.

Spoiler:

  <metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">

  </metadata>

Apparently the refines syntax is wrong and should be:

    <dc:creator id="creator">Crossway</dc:creator>
    <meta property="role" refines="#creator" scheme="marc:relators">pbl</meta>

It's also possible that the Google validator didn't like the older but perfectly vaild syntax of the Sigil version number metadata entry.
