> To support the toleration of duplicate schema components the number of SymbolHash maps stored per SchemaGrammar was doubled and with that significantly increased the footprint of an XSModel.  Many of these maps are usually empty or almost empty, so I plan to reduce their initial size so that they do not waste as much space when they have not been filled.  I also plan to implement a rehash on the SymbolHash to keep the search times down when there are lots of entries.
