- This is the original Base Product Standard introduced in
1992, at a time when the IEEE std. 1003.2 was a Draft 11.2
and nearing ratification. It was intended as a
transitional Product Standard to encourage migration to
the new POSIX-2 standard (ISO/IEC 9945-2:1993 (POSIX-2)).
As far as the Commands and Utilities Product Standard is
concerned, a product registered as conformant to this
Product Standard can be anywhere in the transition path
between the XPG3 state and the POSIX standard, but its
actual state must be clearly defined in its Commands and
Utilities Conformance Statement. Apart from the Commands
and Utilities Product Standard, all other aspects of this
Product Standard are firmly defined, and are identical to
those defined for the Base 95 Product Standard.
Product Standards are explained in Practical Guide to the Open Brand
