Adam,

That is not what I am experiencing.

 

Using IE 6.0.2900.2180, I tried the following scenario to ensure that I am getting "well-formed" XHTML. 

 

a.) From HTML view, I entered:
<p>Hi Mom
<ol>
<li>hi
<li>dad

 

b.) Switched to Normal view and then back to HTML view.  The following was displayed:
<p>Hi Mom
<ol>
    <li>hi
    <li>dad </li>
</ol>

 

c.) Saved the record and the following XHTML was saved in the database:
<p>Hi Mom
</p>
  <ol>
    <li>hi
    </li>
    <li>dad </li>
  </ol>

 

d.) Closed IE, restarted the app and the following was displayed:

<p>Hi Mom
<ol>
    <li>hi
    <li>dad </li>
</ol>

 

What happened to the XHTML?  Why is the ill-formed HTML being displayed?  Does this "transformation" when the data is rendered to the screen a cause of the poor performance?
