>
> Currently, validators have no way of determining whether or not a property
> value contains an Expression Language Expression. This ends up requiring
> processor developers to write code like
> https://github.com/apache/incubator-nifi/pull/36.patch, in which they have to
> check for presence of characters in the value. The onus of this should be on
> the framework.
