   all, what if a node contains some value, but also has some attributes?

positive.code: (**
  
  The function first prints all text included as `<span>` (the element never has any
  attributes in our sample, so it is infered as `string`), then it recursively prints
  the content of all `<div>` elements. If the element does not contain nested elements,
  then we print the `Value` (inner text).
  
  
negative.code: 
  Another interesting case is when there are multiple nodes that contain just a 
  primitive value. The following example shows what happens when the root node
  contains multiple `<value>` nodes (note that if we leave out the parameter to the 
  `Parse` method, the same text used for the schema will be used as the runtime value)
