As long as we dont have these special prefixes, I dont think pure
path access lets you access dictionary values of a script directly.
e.g. here/theScript/key does not work

Another common approach is to call the python Script and
return a ZPT from it via

return context.theZPT(arg1=foo,arg2=bar)

and so on.
