Script bouton google plus et W3c

Bonjour,

Quand je mets cela, avant la fermmeture du head :
<script src="https://apis.google.com/js/platform.js" async defer>
{lang: 'fr'}
</script>

le W3C validator me marque :
Error: The text content of element script was not in the required format: Expected space, tab, newline, or slash but found { instead.
From line 105, column 1; to line 105, column 9
ng: 'fr'}↩</script>↩</hea
Syntax of script documentation:
Zero or more code comments, each of which is either a single-line comment starting with "//" or a multi-line comment starting with "/*" and ending with "*/". The content must also meet the constraints of the script microsyntax. For further details, see Inline

C'est pour mettre le bouton google plus

Merci si vous avez la reponse
