Subject descriptors, keywords and thesauri

Any generic or specialized thesaurus can be used to specify terms in a number of metadata elements of the AKOMA NTOSO metadata section. In particular this is true for the subject descriptors (element name: <keyword>). Whenever a thesaurus is used, the attribute dictionary must be present to specify the name of the thesaurus itself. It is possible to use terms that do not belong to any thesaurus, in which case the “none” value must be used for the dictionary attribute.
