Note:

added:
No, this usage is wrong.  ICARD assumes that data is stored as in Axiom/FriCAS database.  One
can not use a random string here.  Axiom Book gives examples of correct usage.

The ICARD domain implements a container of information about the AXIOM library

ICARD does not work this way, but coercion should yield an error

The IndexCard? documentation says that bad things may happen if the original string is not of the database format.
