facebook & google plugins

Hi,

I was wondering if there was a way of validating my pages without the
validator throwing errors for facebook and google bespoke mark-up / tags?

such as....

<g:plusone

<fb:like 

I have done a search in the archive and found this
http://lists.w3.org/Archives/Public/www-validator/2011Jun/0010.html

But there is no resolve as yet that I can see.

Your advice is appreciated.

Regards,

Craig Chant.
