Note

Each individual keyword (including compound subject headings) should be supplied as a term element directly within the keywords element. An alternative usage, in which each term appears within a item inside a list is permitted for backwards compatibility, but is deprecated.

If no control list exists for the keywords used, then no value should be supplied for the scheme attribute.
