I'm updating my site to AMP but by the time I try to validate I get the following error:
The attribute 'prefix' may not appear in tag 'head'
And the OG namespace declaration uses prefix, how can I workaround this issue?

Facebook sharing doesn't require the prefix attribute. So an easy workaround is to simply omit the prefix attribute. This is how ampbyexample.com does it and it still works:

Nevertheless, the AMP validator should support the prefix attribute. I've filed an issue here.
