Well, it seems that some formating is allowed in <SPAN>, but as far as  
I understand the DTD:

<!ELEMENT DIV - - (%flow;)*            -- generic language/style  
container -->
<!ELEMENT SPAN - - (%inline;)*         -- generic language/style  
container -->

DIV allows only "inline formatting" when span allows "flow"

A flow is "block" or "inline":
<!ENTITY % flow "%block; | %inline;

Hence everything that is a block but not an inline is not authorized in  
a SPAN. This include paragraphs, lists, divs etc...

<!ENTITY % block
     "P | %heading; | %list; | %preformatted; | DL | DIV | NOSCRIPT |
      BLOCKQUOTE | FORM | HR | TABLE | FIELDSET | ADDRESS">

Hence, I wrongly thought that ONLY text was allowed in SPAN, but it  
appears that formatted text is allowed.

Well all of this is purelly theoretical as 99% of the available web  
pages are not valid HTML... but sticking to the standard may be a good  
thing to get cross-plateform web pages...

Regards,

Gilles,
