Hello all,

   I'm trying to write valid xhtml documents in which I have span elements 
whose data I rewrite and whose visibility I modify.  In the course of 
authoring and validating it became painfully obvious that, according to the 
XHTML Transitional DTD, a <span> element may not contain a <p> element (or 
a <div> for that matter).  I was wondering if this is an oversight or, if 
not, what reason would there be to design it this way?

   I have the following snippet of XHTML that I'm trying to validate, but 
of course it complains about the <p>...</p> tag inside of the "span_page1" 
span element.

<table align="center" border="0" cellpadding="0" cellspacing="0" width="90%">
   <tr>
     <td>
       <span id="span_page1" style="display:inline;">
         <p>
Please enter the Mathematical equation that will serve as the
basis for this style of question.  Remember that each equation
basis can create a great number of actual problems, depending
on random number generation and restrictions.
         </p>
         <span id="span_basis" style="display:none;">
           <object id="question" width="500" height="100" 
classid="clsid:5AFAB315-AD87-11D3-98BB-002035EFB1A4">
             <param name="DataType" value="1"/>
             <param name="Data" value=""/>
             <param name="AutoSize" value="true"/>
           </object>
           <br clear="all"/>
           <span id="span_basis_mathml" style="display:inline;">
             <!-- -->
           </span>
         </span>
         <div align="center">
           <input type="button" value="Enter Equation" 
onclick="enterBasis();"/>
           &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
           <input type="button" value="Next" onclick="prepSubmit(1);"/>
         </div>
       </span>
       <span id="span_page2" style="display:none;">
         <p>
Page 2 (Incomplete)
         </p>
         <div align="center">
           <input type="button" value="Back" onclick="presentPage(1);"/>
           &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
           <input type="button" value="..." onclick="javascript:;"/>
           &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
           <input type="button" value="Next" onclick="prepSubmit(1);"/>
         </div>
       </span>
     </td>
   </tr>
</table>

   I need the external-most span element to enable/disable the entire cell 
contents, but it seems that I should be able to space paragraphs out within 
that span, rather than using two consecutive <br /> tags to simulate such a 
break.  Also, it's nice to be able to wrap my text block in its own tag for 
my editor (XML Spy) to indent it properly.

   Any thoughts or replies?
