 # Structure of annotations
-The purpose of this document is to facilitate discussion around the actual structure and scope of standardized annotations for predefined plots.  The starting point is taken from an email previously send to MAP-Lib, which was based on Wolfram SystemModeler's current vendor-specific annotatios, but removing the `__Wolfram` part and just a tiny bit of cleanup.

 ## Naming and grouping of plots
 A Plot may also define a `group` which is a `String` similar to the `group` in the `Dialog` annotation.  It is used to organize plots in models with a large `PlotSet`.
