You're right: A CSV containing only data elements and commas does not carry
the information richness of XML. 

The trick is to give the CSV those capabilities in innovative ways, without
bloating it, and to use it in conjunction with (e.g., as a gateway to) XML
when processing data arrays.

all you've done is shown that the entropy of the xml file is 
significantly lower than the csv file. that would mean it carries 
significantly more information and as others have pointed out, when 
inspecting the xml, this is indeed the case.

put another way the correct interpretation of your experiment is that 
the ratio of the compressed file sizes points to a significant 
difference in information content. the csv file and the xml file aren't 
the same stuff.
