Hi Steve -
This is a good write-up, and important to my development of the ISWA  

Regarding the maximum numbers which you mention in this paragraph...

So here is my question...
Do I need to be sure to not have more than 50 symbols within one  
group, and not more than 5 variations for one symbol?

This is important for me to know, because some of the Movement Arrows  
need more sizes...and the sizes are under the moment  
I don't believe we have more than three possible sizes for any one  
Movement Arrow, but now that I will be expanding it to include more  
sizes, I will make sure that there are not more than 5 sizes for any  
one Movement Arrow...that should be enough and will give the writer  
much more flexibility than what we have now...

So that's cool...;-)

Val ;-)
