Defines specific TIFF fields and parameters for check image exchange and the allowable values for those parameters. This standard will only address the use of G4 bilevel image (black/white) compressions within the TIFF 6.0 structure. A least common denominator approach was used to identify the fields that everyone should read and the required or allowable values for these fields that everyone will be expected to support. To accomplish interoperability, some of the fields and values are more restrictive compared to what is being generated in todays environment. In addition, this standard clarified areas that have been interpreted in different ways.

ISO/IEC TR 19758:2003 provides a DSSSL (ISO/IEC 10179:1996) library that makes it feasible to describe DSSSL specification for documents described by SGML (ISO 8879:1986) or XML (Extensible Markup Language).

The library can deal with some complex compositions programmed by a number of complicated DSSSL specification statements. Those compositions consist of the formatting objects: paper size, paper placement, unit, basic composition style, font, character size, headline, page number, note, inlinenote, emphasizing mark, superscript/subscript, word-length adjustment, character space adjustment, clause, list, table, heading, ruby, paragraph indentation, score, rule, and inline.

The DSSSL library contains the simple parameter data and the four files:

• full parameter generator;
• function set;
• page model set;
• flow object construction rules.

Their actual data are specified in ISO/IEC TR 19758:2003.

Defines the mechanical, electrical, timing, and protocol requirements of the SCSI parallel interface to allow conforming SCSI devices to inter-operate. The SCSI parallel interface is a local I/O bus that may be operated over a wide range of transfer rates. This standard was originally listed for public review in the March 10, 2000 issue of Standards Action. It is being resubmitted due to substantive changes to the text.
