Personally I prefer http://data.london.gov.uk/datafiles/health/alcohol-indicator... and its amazing <Persons_aged_under_18_years_admitted_to_hospital_with_alcohol_specific_conditions_Crude_Rate_per_100000_population_Numbers_-_2005-2006_to_2007-2008> element.
But, as their title suggests, this is a first step.
I noticed this too. As a Londoner, I am pretty excited by this release of data, but, seriously, could they not use attributes for things like the year?!
Embedding the year into the element name, useful that.
