FOREWORD

(This foreword is not part of this Standard.)

"Shall" and "shall not" identify requirements to be followed
strictly to conform to this document and from which no deviation is
permitted. "Should" and "should not" indicate that one of several
possibilities is recommended as particularly suitable, without
mentioning or excluding others, that a certain course of action is
preferred but not necessarily required, or that (in the negative
form) a certain possibility or course of action is discouraged but
not prohibited. "May" and "need not" indicate a course of action
permissible within the limits of the document. "Can" and "cannot"
are used for statements of possibility and capability, whether
material, physical or causal.
