xml-dev - Attributes or not Attributes ?

[Thierry Thelliez <tgt@lanl.gov>]

>From the Microsoft site
http://www.microsoft.com/xml/tutorial/author_doc.asp

there is an example:

<books>
   <book isbn="0345374827">
     <title>The Great Shark Hunt</title>
     <author>Hunter S. Thompson</author>
   </book>
 </books>

why isn't it:

<books>
   <book isbn="0345374827" title ="The Great Shark Hunt" author="Hunter S. Thompson"
   </book>
 </books>

or

<books>
   <book
    <isbn>0345374827</isbn>
     <title>The Great Shark Hunt</title>
     <author>Hunter S. Thompson</author>
   </book>
 </books>

So far I have understood that the 3 notations are legal. But are they identical ?
