Here my rewrite of the first phrase of the 4th paragraph of the scope
note of E59, following Issue 428:

Primitive
Scope Note:This class comprises values of primitive data types of
programming languages or database management systems and data types
composed of such values used as documentation elements, as well as their
mathematical abstractions.
The instances of E59 Primitive Value and its subclasses They are not
considered as elements of the universe of discourse this modelthe CIDOC
CRM aims to define and analyzeat defining and analysing. Rather, they
play the role of a symbolic interface between the scope of
thetthehemodel and the world of mathematical and computational
manipulations and the symbolic objects they define and handle.
In particular they comprise lexical forms encoded as "strings" or series
of characters and symbols based on encoding schemes (characterised by
being a limited subset of the respective mathematical abstractions) such
as UNICODE and values of datatypes that can be encoded in a lexical
form, including quantitative specifications of time-spans and geometry.
They have in common that instances of E59 Primitive Value define
themselves by virtue of their encoded value, regardless of the nature of
their mathematical abstractions.
*Therefore, in an implementation, instances of E59 Primitive should be
represented directly in the encoded symbolic form supported by the
respective platform, such as acharacter string or a formatted date. They
should they must not be represented in an implementation indirectly by
another universal resource identifier which in turn is linked to **the
actual encoded symbolic form**.* In a concrete application, it is
recommended that the primitive value system from a chosen implementation
platform and/or data definition language be used to substitute for this
class and its subclasses.
