According to 13.4 Including an applet: the APPLET element [1], the following
HTML code is valid:
<OBJECT codetype="application/java"
classid="AudioItem"
width="15" height="15">
<PARAM name="snd" value="Hello.au|Welcome.au">
Java applet that plays a welcoming sound.
</OBJECT>
However, the value of codetype is Content-Type [2], and "application/java" is
not a valid Content-Type because it is not registered [3].
