Name of a institution or organization, such as a university or corporation, that is the affiliation for a contributor such as an author or an editor
Conversion Note: In a typical case, the id attribute of an contributor’s affiliation (<aff>), correspondence information (<corresp>), or any footnote in the author note group will be pointed to by one or more Contributor <contrib> elements, thereby linking the two.
However, in those instances in which a symbol or some other mechanism denotes a relationship between a contributor and his/her affiliation, correspondence information, etc., use <xref> to point to the affiliation (<aff>), the corresponding information (<corresp>), or footnote in the author note group.
Conversion Note: Even if the explicitly tagged numbers or symbols for author linkages are preserved during conversion, the linkage from a contributor to an affiliation should be made using the ID/IDREF mechanism during the conversion. The ID/IDREF should be created even if the mechanism must be inserted.
