Draft POSIX Conformance Template for Austin-231 Page 1 of 1
the 1003.13, 2003 Edition PSE54
Submitted by Andrew Josey, The Open Group. December 10, 2004

IEEE Std 1003.13-2003 states

"(1) If the implementation is fully conformant to the referenced base
standard(s), then that implementation may cite the separate conformance
documents that document the base standard conformance. This will primarily
apply to implementations that support the PSE53 or PSE54 Profiles."

If you choose not to cite a reference below follows a sample template
for 1003.1-2001 that you should complete.

Regardless of whether separate base standard conformance documents are cited,
the conformance document for these profile(s) shall contain a statement that
indicates the full name, number, and date of the standard (i.e., the profile
standard) that applies.

The text below is a version of the PCD for 1003.1 with
various options removed that are not applicable to
PSE54 (that is, BE, XSR, most of XSI)

POSIX Conformance Document

Requirements (derived from XBD 2.1.2)

The conformance document shall have the same structure as IEEE Std
1003.1-2001, with the information presented in the appropriate sections
and subsections. Sections and subsections that consist solely of
subordinate section titles, with no other information, are not required.

The conformance document shall not contain information about extended
facilities or capabilities outside the scope of IEEE Std 1003.1-2001.

The conformance document shall contain a statement that indicates the
full name, number, and date of the standard that applies.

The conformance document may also list international software standards
that are available for use by a Conforming POSIX Application. Applicable
characteristics where documentation is required by one of these standards,
or by standards of government bodies, may also be included.

The conformance document shall describe the limit values found in the
headers <limits.h> and <unistd.h> , stating values, the conditions under
which those values may change, and the limits of such variations, if any.

The conformance document shall describe the behavior of the
implementation for all implementation-defined features defined in IEEE
Std 1003.1-2001. This requirement shall be met by listing these features
and providing either a specific reference to the system documentation or
providing full syntax and semantics of these features. When the value or
behavior in the implementation is designed to be variable or customized
on each instantiation of the system, the implementation provider shall
document the nature and permissible ranges of this variation.

The conformance document may specify the behavior of the implementation
for those features where IEEE Std 1003.1-2001 states that implementations
may vary or where features are identified as undefined or unspecified.

The conformance document shall not contain documentation other than that
specified in the preceding paragraphs except where such documentation
is specifically allowed or required by other provisions of IEEE Std
1003.1-2001.

The phrases "shall document" or "shall be documented" in IEEE Std
1003.1-2001 mean that documentation of the feature shall appear in the
conformance document, as described previously, unless there is an explicit
reference in the conformance document to show where the information can
be found in the system documentation.

The system documentation should also contain the information found in
the conformance document.
