I see this mistake everywhere I look, and it's been a problem since before
the days of XML. The cardinal rule when marshalling data should be
"eliminate unnecessary information as early in the process as possible" -
typically in the relational database layer itself. Otherwise, you're just
chewing up bandwidth and memory, and forcing platforms not well suited to
data manipulation (such as XSLT) to do the work instead...
