38 * This structure describes a attset, perhaps made up by inclusion
39 * (supersetting) of other attribute sets. When indexing and searching,
40 * we perform a normalisation, where we associate a given tag with
41 * the set that originally defined it, rather than the superset. This
42 * allows the most flexible access. Eg, the tags common to GILS and BIB-1
43 * should be searchable by both names.
