I think you midunderstand.  Browsers use HTML parsers for the content type
text/html (and IE doesn't doesn't have any other viable option when it
comes to XHTML).  HTML 4.01 allows the implied closure of the <p> element
when it's followed by a block-level element because its content model is
strictly inline.  Hence, to current HTML browsers, this:

<p>This is a paragraph
   <ul><li>which contains a list</li></ul>
</p>

would in practice be parsed as this:

<p>This is a paragraph</p>
<ul><li>which is followed by a list</li></ul>

This would cause problems for both document-manipulating scripts and CSS,
since the selectors 'p ul' or 'p>ul' would never work and
p.getElementsByTagName('ul') wouldn't return any elements.
