@trkurc, this is not a problem fix but an enhancement based on discussion
that occurred on [NIFI-641|https://issues.apache.org/jira/browse/NIFI-641]. It
seemed easy enough, but the validation issues probably out weigh the value.
Postponing until [NIFI-813|https://issues.apache.org/jira/browse/NIFI-813]
provides a means to handle potential errors, but if mixing Regex and Expression
Language can only be handled with a Failure relationships, maybe it's better to
not mix the them and allow separate properties so the Regex can be validated
and the EL expression can produce a list of attributes that can be ignored if
they don't exist. Thoughts?
until they can be added without adding risk.
