ayıptır sorması iframe bunun neresinde ?

aşağıya ufak bi hatırlatma yazıyorum ve el insaf diyorum.
----------------------------------------------------------
<FRAMESET cols="50%, 50%">
<FRAME src="main.html">
<FRAME src="table_of_contents.html">
<NOFRAMES>
<P>Here is the <A href="main-noframes.html">
non-frame based version of the document.</A>
</NOFRAMES>
</FRAMESET>

<IFRAME src="foo.html" width="400" height="500"
scrolling="auto" frameborder="1">
[Your user agent does not support frames or is currently configured
not to display frames. However, you may visit
<A href="foo.html">the related document.</A>]
</IFRAME>
