instruction: provision that conveys an action to be performed [ISO/IEC Guide 2:1996, definition 7.3]
normative element: an element setting out provisions to which it is necessary to conform in order to be able to claim compliance with the Technical Specification
provision: expression in the content of a normative document, that takes the form of a statement, an instruction, a recommendation or a requirement [ISO/IEC Guide 2:1996, definition 7.1]

NOTE:    These types of provision are distinguished by the form of wording they employ; e.g. instructions are expressed in the imperative mood, recommendations by the use of the auxiliary "should" and requirements by the use of the auxiliary "shall" (see annex E).
recommendation: provision that conveys advice or guidance [ISO/IEC Guide 2:1996, definition 7.4]
requirement: provision that conveys criteria to be fulfilled [ISO/IEC Guide 2:1996, definition 7.5]
statement: provision that conveys information [ISO/IEC Guide 2:1996, definition 7.2]

General principles
4.1    Objective
The objective of a 3GPP Technical Specification or Technical Report is to define clear and unambiguous provisions in order to facilitate international trade and communication. To achieve this objective, the 3GPP TS or TR shall:
-    be as complete as necessary within the limits specified by its scope;
-    be consistent, clear and accurate;
-    provide a framework for future technological development; and
-    be comprehensible to qualified persons who have not participated in its preparation.

4.2    Homogeneity
Uniformity of structure, of style and of terminology shall be maintained not only within each 3GPP TS or 3GPP TR, but also within a series of associated 3GPP TSs or 3GPP TRs. The structure of associated 3GPP TSs or 3GPP TRs and the numbering of their clauses shall, as far as possible, be identical. Analogous wording shall be used to express analogous provisions; identical wording shall be used to express identical provisions.
The same term shall be used throughout each 3GPP TS or 3GPP TR or series of 3GPP TSs or 3GPP TRs to designate a given concept. The use of an alternative term (synonym) for a concept already defined shall be avoided. As far as possible, only one meaning shall be attributed to each term chosen.
These requirements are particularly important not only to ensure comprehension of the 3GPP TS or 3GPP TR but also to derive the maximum benefit available through automated text processing techniques.

4.3    Consistency of 3GPP TSs and 3GPP TRs
In order to achieve the aim of consistency within the complete body of 3GPP TSs and 3GPP TRs, the text of every 3GPP TS and 3GPP TR shall be in accordance with the relevant provisions of existing basic 3GPP TSs and 3GPP TRs. This relates particularly to:
-    standardized terminology;
-    principles and methods of terminology;
-    quantities, units and their symbols;

-    abbreviations;
-    bibliographic references; and
-    graphical symbols.
In addition, for specific technical aspects, the relevant provisions of general 3GPP TSs or 3GPP TRs dealing with the following subjects shall be respected:

-    limits;
-    tolerancing of dimensions and uncertainty of measurement;
-    preferred numbers;
-    statistical methods;
-    environmental conditions and associated tests.

4.4    Equivalence of official language versions
3GPP TSs or 3GPP TRs shall be in the English language only.

4.5    Fitness for implementation as a national, regional or international standard
The content of a 3GPP TS or 3GPP TR shall be drawn up in such a way as to facilitate its direct application and its adoption without change as a national, regional or international standard.
