anchor.diff:    when the schema changes).
   * Optional client-side caching of schema information makes type checking quick and efficient
   * Units of measure are supported. For example, the `Atomic mass` property of chemical elements
  -  is automatically converted to SI units and it is exposed in Killograms. This is statically
  +  is automatically converted to SI units and it is exposed in Kilograms. This is statically
     tracked in the F# type system using units of measure.
   * If you want to query larger amount of Freebase data, you can register at Google and
     obtain a custom API key. The key can be passed as a static parameter to the type provider.
  
positive.code: filter the data or perform other querying.
  
  However, the Freebase provider includes support for querying. Queries written using the
  F# 3.0 LINQ syntax are translated to MQL (a querying langauge used by Freebase). This means 
  you can write queries in F# 3.0 with auto-completion and strong typing, and still execute 
  efficiently on the server, at least for the queries translated to MQL.
  
  
negative.code: ### Exploring Freebase data
  
  Now you can explore the Freebase data schema by typing `data.` and exploring the
  available data sources in the autocomplete. For example, the following snippet
  retrieves the Chemical Elements and then looks at the details of Hydrogen:
