Re: [JDEV] Protocol bits and discussion

[Robert La Quey <robertl1@home.com>]

I have been lurking or some time following the 
development of JABBER with great interest. This 
is a great development. 

I will just jump in here with some general questions 
about XML design which have come up on another list.
JABBER provides a good example of the issues. I am not
quarelling with the approach Jeremie has taken but 
would like to understand the design issues better.

An alternative would be 
<login user="test" pass="test" nick="test user" >
</login> 

etc ... when and why does one use tags versus 
providing attributes to tags? 

Does it matter?

<message session="you" thread="sdfa" priority="1" subject="Did you see that?">
	<say> hfj l J Fkf  hgkl;jasda</say>
</message>

etc. I think you get the question and can see the issues. 
the XML parser should not care. It will just as readily 
parse out attributes as tags ...

What are your thoughts?
