Point 1:

[[
Formally, a datatype d is defined by three items:

1. a non-empty set of character strings called the lexical space of d;

2. a non-empty set called the value space of d;

3. a mapping from the lexical space of d to the value space of d, called 
the lexical-to-value mapping of d.

The lexical-to-value mapping of a datatype d is written as L2V(d).
