I should note that you can, pretty easily, create a translation that would take
the XML below - from a file or whatever - parse it and turn it into the
dictionary using any of the discussed encoding. The "end user" would see only
the perfect XML encoding. The consumer - i.e. the service implementing the
ManagedService interface - which actually uses the dictionary doesn't, or
really shouldn't, care about prettiness. Rather all they have to do is get the
data and know how to do it.
