<br />One of the problems is that XHTML requires &quot;well-formed XML&quot;, and many books
<br />simply are  not structured in a rigorously well-formed way.
<br />
<br />But in any case it seems to be the common view that it simply hasn&#39;t gained
<br />useful traction and now it&#39;s just overhead.

<br />&gt; 
<br />&gt; Wrong. XHTML IS specified! Besides HTML is a backwater and
<br />&gt; 
<br />&gt; the W3C would like it to disappear.
