> Regarding JBRULES-2823: I don't know how to supply a patch for the fusion user guide, so I'll just type here:
> To the orginal: 
> "For instance, if the user wants to consider only the last 10 IBM Stock Ticks, independent of how old they are, the pattern would look like this:
> StockTick( company == "IBM" ) over window:length( 10 )
> As you can see, the pattern is similar to the one presented in the previous section, but instead of using window:time to define the sliding window, it uses window:length."
> you should append the following to clearify:
> "Be aware that only literal conditions are applied before the window is applied. So the following rule would consider only the IBM stock ticks WITHIN ALL last 10 stock ticks:
> @company : Company(name == "IBM")
> StockTick( company == @company ) over window:length( 10 )
> "
