[IPT] how to do when you have more than one sampling method for the same plant plot

Hi all,
Thanks, Andrea and André :-) for your replies.
Just to be clear, this is how I should do:
In the event core, I leave `samplingProtocol` blank, because each event
will have two sampling methods. The sampling method should be included
in `measurementType`of the (Extended)MeasurementsOrFacts DwC Extension.
If using the ExtendedMeasurementsOrFacts, as Andrea recommends, I should
include the occurrence ID from table occurrences in the column
`occurrenceID`.
Is this correct?
I am curious what will happen when GBIF ingests the data. Will any of
the sampling methods be associated with the occurrences?
Cheers,
Rui
