-/**
- * Attribute vector which does not store values of its own, but rather serves as a
- * convenient indirection wrapper towards a target vector, usually in another
- * document type altogether. Imported attributes are meant to be used in conjunction
- * with a reference attribute, which specifies a dynamic mapping from a local LID to
- * a target LID (via an intermediate GID).
- *
- * Any accessor on the imported attribute for a local LID yields the same result as
- * if the same accessor were invoked with the target LID on the target attribute vector.
