Provides access to a specific attribute name
mapping by its name. If the requested mapping does
not exist yet, a new mapping will be created, added
to the set of managed mappings, and returned. This
means, this method will always return a mapping,
but this could be empty.

@param name Name of the requested mapping.
@return The requested mapping, as stored in this
facility (or newly created).
