The e-junkie Add-to-Cart button code includes this: <script language="javascript" type="text/javascript"> but HTML 5 does not permit the attribute "language" in the <script> tag. The button still seems to function normally when I remove the language="javascript" attribute (that is, it seems to be working in the browsers I use to check code), but I'm wondering what, where (and if) I'm going to get bit removing this attribute?
