Display of containers as string now handles repeating values as expected. For a container with the following structure:

ca_collections.extent
	ca_collections.extent_value
	ca_collections.extent_units

the template '^extent_value ^extent_units' used to return this:

'40 73 linear feet document boxes'

It now returns this:

'40 linear feet 73 document boxes'

Add a delimiter in there and you have decent output now
