Brief text describing or providing context for the text author or corporate source, at the publisher’s discretion, and intended to be used in addition to <TextAuthor> or <TextSourceCorporate>. Optional, and repeatable to provide parallel descriptions in multiple languages. The language attribute is optional for a single instance of <TextSourceDescription>, but must be included in each instance if <TextSourceDescription> is repeated. The description may be used with either a person or corporate name, to draw attention to any aspect of the text source’s background which provides context for the text in <Text>.
