When configuring a Noification with a REST Delivery Endpoint, there is no way to escape a dot (".") so it doesn't gets interpreted as a path delimiter. There are cases when the dot must be part of the property name. One way to solve it would be to allow escaping it with a backslash or even better (IMHO) to use the JSONPath way to solve this: being able to specify arbitrary property names putting them between brackets and single quotes: ['prop.erty'].
