ISO 18443:2016 Practice defines extensions to the SLE API in terms of:

a) the RCF-specific functionality provided by API components;

b) the RCF-specific interfaces provided by API components; and

c) the externally visible behavior associated with the RCF interfaces exported by the components.

It does not specify:

a) individual implementations or products;

b) the internal design of the components; and
