  +This code builds a type `Rss` that represents RSS feeds (with the features that are used
   on `http://tomasp.net`). The type `Rss` provides static methods `Parse` and `Load`
   to construct it - here, we just want to reuse the same uri of the schema, so we
   use the `GetSample` static method:
  
positive.code: It takes a sample document as an input (or document containing a root XML node with
  multiple child nodes that are used as samples). The generated type can then be used 
  to read files with the same structure. If the loaded file does not match the structure 
  of the sample, an exception may occur (but only when accessing e.g. non-existing element).
  
  ## Introducing the provider
  
  
negative.code: If the node cannot be represented as a simple type (like `string`) then the provider
  builds a new type with multiple properties. Here, it generates a property `Full` 
  (based on the name of the attribute) and infers its type to be boolean. Then it
  adds a property with a (special) name `Value` that returns the content of the element.
