OK figured out a workaround:
def isnotempty(value):
return bool(value)
layers = schema.List(
title=_(u"Layers"),
description=_(u"WMS Layers"),
required=True,
constraint=isnotempty,
value_type=schema.Choice(
source=layers_vocab,
required=True,
),
)

If you save the living environment, the biodiversity that we have left,
you will also automatically save the physical environment, too. But If
you only save the physical environment, you will ultimately lose both.
1) Don’t drive species to extinction
2) Don’t destroy a habitat that species rely on.
3) Don’t change the climate in ways that will result in the above.
