Hi Ed,

You should assign multiple metadata values to the same metadata element,
then specify the "-allvalues" option to the Hierarchy classifier.

If the items in the classifier should be in alphabetical order then you
don't need to create a hierarchy text file: you can just assign the
values using "|" to separate the levels and the Hierarchy classifier
will sort it out.

All the best,
