from any observables (at least from the hilite handler right now). All

.
Similarly, the returned output specs need to comply with their port types
spec class (otherwise an error is reported by the framework). They may
also be null.
For a general description of the configure method refer to the
description of the specialized NodeModel.configure(DataTableSpec[])
methods as it addresses more use cases.

just check them. If some settings are missing, invalid, inconsistent, or
just not right throw an exception with a message useful to the user.
