The end result of this partnership should be: 1.) Clear use of Variable Scoping (in Include, Function, and Text / Math = variables=85 as well as the ancillary tags/contexts, such as = [ListVariables..]) 2.) Refinement of the Include tag=92s feature of =93&varname=3Dvalue=94...= addressing encapsulation.=20 3.) Clear documentation of all of this.=20 There is a real opportunity here (in my opinion) to bring WebDNA to a = new level of sophistication / maturity.
