I attended a talk on DB'2 XML Viper stuff the other day. And they were 
touting its high performance XML/XQuery support for stuff like this 
(their favorite example seems to be meeting appointments). Essentially 
they were saying a lot of things simply do not fit a fixed storage 
layout, but there are enough similarities between data sets that you can 
still benefit from indexing things.

However their stuff also supports nested structures due to their XML 
nature. Also due to the XML nature you can optionally check all data 
going in to follow an xsd to prevent people from going all too crazy.
