I'm trying to use collective.simplesocial on my diazo-themed site (Plone 4.1), and notice the like button was broken.
The <fb:like> tag was transformed to <like> (the prefix is stripped). All other xfbml tags suffered the same problem.
I've tried to add xmlns:fb="http://www.facebook.com/2008/fbml" to html tag but it didn't work either.
Any idea to overcome this ?
This should work for the plusone button (see comment for answer to your original question):
<xsl:template match="plusone">
<xsl:element name="g:{local-name()}" xmlns:g="http://base.google.com/ns/1.0">
<xsl:apply-templates select="@*|node()"/>
</xsl:element>
</xsl:template>
