I've not used the directive, but from the documentation "schema" is the
schema provided by the object, not the interface of the field:
If you have:
class ISpeciesData(...):
speciesList = schema.List(...)
you give your.package.interfaces.ISpeciesData to the "schema=" attribute
and your template will be picked up by all MultiWidgets displayed for a
field from ISpeciesData.
You can make the registration more specific with the other attributes
available for z3c.widgetTemplate, like "layer", "field" of "view".
"view=...IDistributionView" alone should work to overwrite the multiwidget
template for this view.
