For example, it -- -- includes additional with-clause dependences, comments, and -- -- complete definitions for certain types, ranges, and constants that -- -- are left implementation-defined in the draft standard. These -- -- differences appear to be within the scope of variation which the -- -- draft standard permits for implementations, but no warranty is -- -- made to that effect. -- -- -- -- These package specifications are distributed in the hope that they -- -- will be useful, but WITHOUT ANY WARRANTY; without even the implied -- -- warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. -- -- -- -- The package specifications in IEEE Draft Std 1003.5b/D5 represent -- -- only a portion of the document and are not to be interpreteted -- -- outside the context of the document, nor is the draft document to -- -- be interpreted as an approved consensus standard. -- -- -- -- When IEEE Std 1003.5b is approved, it must be used in conjunction -- -- with the final version of the package specifications contained in -- -- that document in order to claim conformance. The IEEE takes no -- -- responsibility for and will assume no liability for damages -- -- resulting from the reader's misinterpretation of said information -- -- resulting from its out-of-context nature.
