The specification lives at https://docs.djangoproject.com/en/1.6/ref/settings/#template-loaders and the example above is described at https://docs.djangoproject.com/en/1.6/ref/templates/api/#django.template.loaders.cached.Loader

See current implementation at

django-confit/django_confit/schemas/django.py

Lines 879 to 886 in b02fe8f

	TEMPLATE_LOADERS = colander.SchemaNode(
	colander.Sequence(),
	missing=global_settings.TEMPLATE_LOADERS,
	default=global_settings.TEMPLATE_LOADERS,
	children=[
	colander.SchemaNode(colander.String()),
	]
	)

Perhaps try to use the accept_scalar option for colander.Sequence.

If it does not work, let's check whether having a "String or Sequence" type is easy or hard. Where"String or Sequence" may look like TupleOrNone but may also be configured (something like OneOfTypes(Sequence(...), String(...))?

Else fallback to a more flexible validation, even if it is "weak". I mean, at the moment with django-confit, making a valid schema pass is more important than making an invalid schema fail: the first goal is to support Django's settings. Later, we may setup smarter validators.

accept_scalar does not make the job :/ If I find something better or if I can implement the OneOfTypes way I'll try to make a PR. But List if a temporary good fix.
