[uf-discuss] class="url"?

[Siegfried Gipp]

Just a question:

for what purpose is the class="url" as attribute of a link?

Example from the hCalendar spec:
<span class="vevent">
 <a class="url" href="http://www.web2con.com/">
  <span class="summary">Web 2.0 Conference</span>: 
  <abbr class="dtstart" title="2005-10-05">October 5</abbr>-
  <abbr class="dtend" title="2005-10-08">7</abbr>,
 at the <span class="location">Argent Hotel, San Francisco, CA</span>
 </a>
</span>

So what does the <a> container contain? It contains a summary, two dates and a 
location. Does it contain a url? I can't see any.

The href attribute of the <a> container on the other hand does contain a url. 
It has to contain a url according to the html and xhtml specifications. 
Although this url does not need to be a full url. So, the simple usage of the 
<a> tag (as well as the <link> tag already implies the presence of a href 
attribute which according to specification has to contain a url. The same 
goes for img and the src attribute and with object and the data attribute. So 
here the class="url" is not only unnecessary, it is wrong, since the <a> 
container does not contain a url.

Other example:
see here: <a href="http://www.web2con.com/">http://www.web2com/</a>

This indeed does contain a url. So here it would be o.k. to use the 
class="url":
see here: <a href="http://www.web2con.com/" 
class="url">http://www.web2com/</a>

Generally, class="url" is not unnecessary per se, but it is wrong in all 
examples in the wiki. The only correct usage of class="url" would be if that 
html container indeed contains a url.
