RE: question: Increasing factor for XML vs Binary

I think that there are a number of use cases where chunking is not going
to help.  Sending location and map data to mobile phones is probably
one.  The issue is how many bits, not how many pieces they come in. The
floating point data usage case from the energy industry (which I
contributed) is definitely not going to be helped by chunking.  That
would only make things worse -- it would not address the primary issues
whatsoever.
 
I don't know what subclass of usage cases chunking would address, but my
impression is that it is fairly limited.

Hi,

Following is a private message to me from a kind person.
Maybe I should wait for him to write this, but I wish to share what he
told me to you.

Why is XML unnatural here?  I can see that the XML documents could
become  very large, but a binary XML representation is only likely to
win you an  improvement of 10-30, and that only sounds like a short
reprieve to me.   You have have to end up chunking the data somehow, and
once you do that,  the chunked XML could be quite manageable.

    Cheers, 
        Tony.

	Hi all, 
	        I would like to know the estimation order of the
increasing factor for the XML format respect to the equivalent binary
product, I mean, which is the order of the overload that will supose
using XML instead of binary format? 
	
	Thank you very much, 
	Best regards,
