/** A mapping from a (source) set of XContentIdentifiers to another (target)
    set of XContentIdentifiers.  For convenience and performance, mapping
    between the string representations of source/target XContentIdentifiers,
    as well as mapping between XContents identified by source/target
    XContentIdentifiers is also supported.

    @descr  This interface can be useful in cases where the identifieres (and
    associated contents) returned by the various methods of an XContentAccess
    need to be mapped to some other space of identifiers (and associated
    contents).
