The original poster mentioned CSVs which for all intents and purposes will
always be smaller files than their XML counterparts. For complex data I assume
ASN.1 could also represent the same data as XML but use less bytes to do it (I
haven't used it just know developers who have) or even better any homegrown
data format built specificially for that purpose would be more space efficient
than XML.

In general case if one uses a minimal subset of XML for serialization then
there is little complexity and XML lives up to its reputation for being
simple. However in a few places where XML is being suggested as a
serialization format there is reliance on multiple XML technologies meaning
that developers have to become conversant with namespaces, schemas,  WSDL,
SOAP, etc.  where it may have been better to use domain specific technologies
instead of interedependent XML ones since there is less chance of information
overload on the part of the developer.

It doesn't, my point here was that in for some people (such as the IBM
mainframe folks until XML 1.1) XML was unsuited to some of their data
serialization needs due to its original intent as a text-based technology.

I agree, serialization using a _subset_ of XML is typically a good idea.

I will hire an expert marksman to stand by the entrance to my fortress.
His job will be to shoot anyone who rides up to challenge me.
