Repetition of Normative References (1 Introduction)

1 Introduction reads in part:

*****
These rules presume the reader is already familiar with the following and this document makes no attempt to reiterate any or all definitions, principles, rules, syntax or constraints found in the following:

the principles of ISO/TS 15000-5:2005 Core Component Technical Specification [CCTS - ISO/TS 15000-5:2005];

the principles of ISO/IEC 11179 Data Elements [ISO 11179];

the semantics and syntax of W3C XSD [XSD schema] for XML document constraint specification;

the semantics and syntax of OASIS Context/value association using genericode [CVA] for code list association; and

the semantics and syntax of OASIS genericode [genericode] for code list representation.

Naming and design rules govern the application of the above works to the objective of creating concrete user data validation artefacts from abstract information bundles.

That leaves me with the impression that these are normative references which govern the use of this document.

To that extent, it is a duplication of the normative reference list at: 1.2 Normative References.

However, the list of normative references in 1.2 omits "the principles of ISO/IEC 11179 Data Elements [ISO 11179];" which is cited in 1.3 as a non-normative reference.

Thus creating a conflict between the informal statement of normative references and the formal statement of normative references.
