As per HTML standards the script language attribute is now considered obsolete. There are 10 files in FarCry core that still use the language attribute.
/packages/formtools/longchar.cfc
/packages/formtools/richtext.cfc
/packages/fourq/tags/timer.cfm
/tags/formtools/objectadmin.cfm
/tags/webskin/flexWrapper.cfm
/webskin/dmCategory/webtopBodyQuickBuilder.cfm
/webtop/conjuror/edit.cfm
/webtop/thirdparty/checkboxtree/checkboxtree.cfm
/webtop/thirdparty/tiny_mce/plugins/farcrycontenttemplates/popup.cfm
/webtop/edittabRules.cfm
The problem (for those trying to pass site compliance checks) only comes from those that output to the frontend.
It would be better to have the output as <script type="text/javascript">
rather than <script language="javascript">
