This is used in conjunction with the EMBED element to indicate content/HTML
markup that will only appear if the browser does not support the EMBED syntax.
Browsers that DO support the EMBED element will ignore the contents
of the NOEMBED element.
There is ambiguity about whether the EMBED element is a container or not.
If it is a container (which several references say it is) it would make
the content of the element invisible to supporting browsers. Browsers that
do not support EMBED would thus be able to see the EMBED element content.
This line of reasoning would seem to make the NOEMBED element useless. I
personally do not yet know the answer to this yet so keep this ambiguity in mind.
DTD Note: The Parent/Content models used for this
element are taken from the NOSCRIPT element, which appears to have the
same usage intent.
Browser Peculiarities
Support Note: Internet Explorer does appear
to support this element. All content within NOEMBED does not appear.
If loading of plug-ins is disabled however, the content still does not appear.
This behavior is different than for similar elements like NOSCRIPT.
