wpSpaceWidth : unknown application behaviour

Proposed Disposition of DIS 29500 Comment KR-0017 (Modified: 2007-12-20) Agreed; we will fully define the information necessary to implement this property (specified below). This description provides all of the information needed to mimic a behavior observed in a previously existing word processing application (WordPerfect 5.x). In addition, we will remove it from its current location in the specification (Part 4, §2.15.3.66, page 1,485), and place it into a new annex for deprecated features. Following the precedent set by other ISO standards (such as SQL’s ISO 9075:2003 Part 1 and C++’s ISO/IEC 14882:1998), we will make use of a new Annex that contains normative descriptions of all deprecated features. The intent of this Annex is to enable a transitional period during which existing binary documents being migrated to DIS 29500 can make use of those deprecated features to preserve their fidelity, while noting that new documents should not use them. Accordingly, the Conformance clause will also be changed to state that newly created documents (those not created by migrating existing binary documents) should not use deprecated features. All deprecated features will be removed from their current locations in the standard, but will be fully defined in this new Annex. To provide a full description, the existing text in Part 4, §2.15.3.66, page 1,485, lines 56, will be replaced with the following: 2.15.3.66 wpSpaceWidth (Use Specific Space Width) (The terms ascent and descent are used as defined in ISO/IEC 14496-22:2007.) This element specifies that applications should perform determine the width of the space character for all proportional fonts used in this document using the calculation specified below. Typically, applications calculate the width of a whitespace character dynamically to optimize for the output device. This element, when present with a val attribute value of true (or equivalent), specifies that applications should instead use the following algorithm to determine the width of a whitespace character: = + 3 where is the width of a space character is the ascent for the font is the descent for the font [Example: Consider a WordprocessingML document with this compatibility setting turned on: <w:compat> <w:suppressTopSpacingWP /> </w:compat> If the font applied to a run specified an ascent value of 8 points and a descent value of 2 points, each space in that run would have a width of three and one-third points. end example] Similar Comments: CL-0106 , CO-0114 , CZ-0024 , DK-0021 , FR-0071 , GB-0239 , GR-0042 , IN-0039 , IR-0029 , PT-0056 , US-0070
