if true, the variables will be merged strictly into the local scope (as indicated by
elementInstanceKey); this means the variables is not propagated to upper scopes.
for example, let's say we have two scopes, '1' and '2', with each having effective variables as:
1 => { "foo" : 2 }, and 2 => { "bar" : 1 }. if we send an update request with
elementInstanceKey = 2, variables { "foo" : 5 }, and local is true, then scope 1 will
be unchanged, and scope 2 will now be { "bar" : 1, "foo" 5 }. if local was false, however,
then scope 1 would be { "foo": 5 }, and scope 2 would be { "bar" : 1 }.
