title: RegionInfo as a reliable source for currency formatting
body: <p>We are investigating how best to store currency information, including display format and importantly the number of decimal places.  This data is available between RegionInfo and CultureInfo in .Net, but I'm not convinced that this data is reliable, given the volatile nature of countries like Zimbabwe (Zim is actually currently up-to-date with USD).  However, it seems unwise to replicate behaviour and data that these classes already provide.</p>
  
  <p>Is there any good reason to avoid RegionInfo/CultureInfo and rather replicate and customise the data they provide?</p>
