Some newbie questions about:

 http://www.w3.org/TR/2001/WD-xml-events-20011026/ 

Why is the "attribute defaulting" mechanism defined for determining
the observer element instead of requiring the observer be explicitly
defined?  Does the fact that an element may be an [implied] observer
element supposed to be reflected into the document's DOM or Infoset?
What are the implications of this mechanism for streaming/SAX-based 
applications and parsers?

WRT the Basic XML Events Profile, wording such as "may be required" 
begs - what are the specific requirements for a conforming user agent?  
Will the restrictions be reflected in a DTD/module?  In 2.6.#1, when 
it says "the following is not required to be processed", does that 
mean the handler is ignored or the entire listener element is ignored?

What is the purpose of a listener element with no observer attribute
and no target attribute?

Besides X-Smiles, are there other implementations of XML Events?

The HTML WG's Roadmap page (Member only?) projects a Candidate
Recommendation for XML Events on Jan 14.  Is that projection on 
target?

Thanks,

Art Barstow
