Used in text

For example, this tag:

<embed src=movie.avi width=320 height=200 autostart=true loop=3>

has attributes that are processed by the <embed> tag ( src , width , and
height ), and two that are not recognized, but rather are passed to the
plug-in associated with AVI video clips: autostart and loop . [*]

[*] Internet Explorer has built-in support for AVI movies; other browsers require that users download and
install a plug-in that plays the AVI movie.
