user: Should user-defined attributes be returned? The default of NULL returns all xts attributes.
value: A list of new name = value attributes.

Value

A named list of user-defined attributes.

This function allows users to assign custom attributes to the xts objects, without altering core xts attributes (i.e. tclass, tzone, and tformat).
