(What about zero?) 4.7.4 para 2 says: "If there are two sub-pictures, then these rules are applied to one sub-picture to obtain the values that apply to positive numbers, and to the other to obtain the values that apply to negative numbers. " 4.7.5 rule 2 says: "In the rules below, the positive sub-picture and its associated variables are used if the input number is positive, and the negative sub-picture and its associated variables are used otherwise. Negative zero is taken as negative, positive zero as positive." (This implies that for decimals, where zero is unsigned, the negative sub-picture is used to format decimal zero, which would lead to it having a minus sign prepended.) I think the problem is essentially editorial, there's no room for doubt about the intent, but it definitely needs tidying up. 119810 1 mike 2015-04-23 15:24:35 +0000 I propose the following changes: 4.7.3 bullet 1 says "If the picture-string contains two sub-pictures, the first is used for positive *and unsigned zero* values, and the second for negative values." 4.7.4 para 2 says: "If there are two sub-pictures, then these rules are applied to one sub-picture to obtain the values that apply to positive *and unsigned zero* numbers, and to the other to obtain the values that apply to negative numbers. " 4.7.5 rule 2 says: "In the rules below, the positive sub-picture and its associated variables are used if the input number is positive, and the negative sub-picture and its associated variables are used *if it is negative. For xs:double and xs:float, the negative sub-picture is used for negative zero, the positive sub-picture for positive zero. For xs:decimal and xs:integer, the positive sub-picture is used for zero.*" 120086 2 mike 2015-05-05 17:22:12 +0000 The change was accepted and has been applied.
