#1 no type restriction in a V1 architecture

[Hartmut Jürgens]

In the V1 only Object, int and boolean expressions
could be used. The V2 hasn't this restrictions but an
addiotionally compilation is necessary. I would like to
hear about plants to update the V1 architecture because
the main advantage of the rule engine to me is the
possibility to change application behaviour w/o
touching the code.
