Subject: Re: [office-comment] Further comment on ODF_1.0_Errata_draft_3
Patrick, It seems to me that the source of ambiguity and possible implementer confusion is removed by deleting the parenthetical observation if it is clear that the syntactically-allowed and the semantically-allowed values are coextensive. (I, for one, have my doubts about negative "physical lengths" especially when "magnitude" is used in the explanation.). Maybe it is better to remove the parenthetical remark and add the statement "Note that negative lengths are allowed. Compare with nonNegativeLength and positiveLength." although I would love to know how negative lengths are treated (and I am not going to go looking at this point, trusting that the definition of attributes having this kind of value are sufficiently precise). I agree that the schemata given for lengths in the ODF schema are definitive with regard to the syntax (but notice that the non-zero constraint for positiveLength is expressed in a comment, not in the pattern. - Dennis -----Original Message----- From: MURATA Makoto (FAMILY Given) [mailto:eb2m-mrt@asahi-net.or.jp] http://lists.oasis-open.org/archives/office-comment/200809/msg00023.html Sent: Tuesday, September 16, 2008 06:49 To: office-comment@lists.oasis-open.org Subject: [office-comment] Further comment on ODF_1.0_Errata_draft_3 First, I am happy with the way that the errata has been prepared. I will review the content, but here is a comment. >N0492:74 “Is zero allowed as a length in Chap 10? "A (positive or >negative) physical length" (page 691) appears to disallow zero.” > >Rejected, not a defect. The expression syntax referenced from this >definition, XSL 1.0, 5.9.11, clearly allows zero. I would argue that this is a defect, since zero is neither postive nor negative. People use the phrase "non-negative integer" precisely because of this reason.
