Sigh most of that was lost somewhere ... I'm on a handheld ...

I'll interperet this as 'how much of a compression factor can be achieved by using a binary vs XML encoding of the same data.'  The usual answer, I'm afraid: it depends.  As best I recall from a literature survey:

larger docs compress better than small,

you can get more compression if you use more CPU (and hence battery) power,

you can get very good compression if you assume that the schema is known to both sides and docs are valid instances,.

My recollection is that 5:1 compression is realistic for arbitrary XML and 10:1 and higher is feasible with shared schemas.

Subj:  question: Increasing factor for XML vs Binary 

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 

Thank you very much,
Best regards,

Silvia de Castro.
