	Purpose and justification:

	The National Profiles described in ISO 9945-1 (POSIX) and ISO
	9945-2 form a set of POSIX profiles.  The National Profile will
	be developed by national member bodies of ISO/IEC and specify
	required options, parameters, and extensions of POSIX standards
	that a <National body> conforming implementation shall support.

	A National Locale described in ISO 9945-2 is a part of user
	environment specificatios that are culture or language specific.
	A National Locale is referred to by APIs and utilities to adapt
	their behavior to the users' language and cultural background.

	National member bodies of ISO/IEC can specify required or
	recommended options and parameters of POSIX standards through a
	National Profile.  Also the national member body can specify the
	cultural element relevant to their environment through a
	National Locale, in order to adapt an implementation of the
	POSIX standards to their regional or cultural environment.  From
	a view point of a <National body> conforming application, the
	National Profile and Locale specify the functionalities that the
	application can rely on for being portable within the regional
	or cultural environment.  However, such regional specific
	dependency may hurt international portability of the
	appilcation. Therefore, to maximize international portability of
	a <National body> conforming application, international
	harmonization of National Profiles and Locales is important.
	The proposed Technical Report "Guide for POSIX National Profiles
	and Locales" establishes guidelines that a writer of National
	Profiles and Locales would refer to.  Then a national member
	body of ISO/IEC can easily develop their National Profile and
	Locale that harmonized internationally.

	The Technical Report will have the following table of contents.
