Current Weather Conditions in XML from the National Weather Service
(http://www.weather.gov/xml/current_obs/KBOS.xml:

Observations on XML

• Data-centric and complete
• Use of "string" representations
• RFC822 Time
• Element-based
• "Flat" structure
• Element names contain metadata ("temperature_c")
• Not valid because of "NA" in "xs:integer" field
