[microformats-discuss] hCard clarifications

[Eran]

Looking at the specs for hCard and at some of the examples I've come
across a slight variations, I'm looking at complex elements like adr. 

http://www.crowley.nl/hcard.html includes an adr field composed of
several "sub"-fields (although it neglects to separate them with a
semicolon):

<div class="adr">
  <div class="street-address">Waarderweg 52d</div>
  <span class="postal-code">2031BP</span>
  <span class="locality">Haarlem <abbr
title="Netherlands">NL</abbr></span>
 </div>

http://home.alltel.net/jackwolfgang/blog/2005/06/microformats-resume-upd
ate.html used the sub-fields without the containing adr field:

<div class="vcard Centered">
 <a href="http://home.alltel.net/jackwolfgang/" target="_self" 
  class="url fn n" rel="me">
  <span class="given-name">Jack</span> L.
  <span class="family-name">Wolfgang</span>
  II</a><br />
 <span class="locality">Cairo</span>,
 <span class="region">Georgia</span>,
 <span class="country-name">

  <abbr title="United States of America">USA</abbr></span>
 <span class="postal-code">39827</span><br />
 <a href="../contact/" target="_self" class="email">E-Mail 
  via Web Form</a><br />
</div>

Are both correct? What exactly are the rules for using complex fields?

While I'm here, another question on multiple classes. For example the
following element:

<a href="http://home.alltel.net/jackwolfgang/" target="_self" 
  class="url fn n" rel="me">
  <span class="given-name">Jack</span> L.
  <span class="family-name">Wolfgang</span>
  II</a>

What are the rules for interpreting the "url fn n" class string? Is
there a relation between the order of classes in the class string and
the href & text properties of the A element?

TIA,
Eran.
