chrome support for msxsl:script

Question

I have a requirement where I have to call functions in xsl:value-of select=<Function Name>. The below code helps me do it in IE, but I need the same alternative for Chrome.

<xsl:value-of select="xslscript:ConvertDate()"/>

      <msxsl:script language="javascript" implements-prefix="xslscript">
     function ConvertDate()
    {
                 /*Function body*/
    }

... where msxsl is the namespace given by Microsoft (xmlns:msxsl="urn:schemas-microsoft-com:xslt").

I need the same support for Chrome. Please let me know how can I call the ConvertDate method, as I do not have msxsl namespace support for Chrome, since this is given by Microsoft and it is IE specific.
