http://www.w3.org/Bugs/Public/show_bug.cgi?id=6314 Summary: XPath subset for assertions Product: XML Schema Version: 1.1 only Platform: PC OS/Version: Windows NT Status: NEW Severity: normal Priority: P2 Component: Structures: XSD Part 1 AssignedTo: cmsmcq@w3.org ReportedBy: mike@saxonica.com QAContact: www-xml-schema-comments@w3.org This is raised in response to some discussion on xml-dev today which points out that the specs are unclear on a significant question. In the status section of the current published working draft we say: "The minimal subset of XPath which processors were required to support for assertions has been eliminated; processors must support all of XPath." But in section 3.13.1 Assertions we say (and this is still in the status quo): "Conforming processors may implement all of [XPath 2.0] or may restrict themselves to the subset described below. Interoperability among all conforming implementations is best achieved by restricting XPath expressions to the subset." Moreover it's not very clear what "below" refers to. The sentence quoted is followed by some very informally-stated rules like "Path steps are restricted to only match information items within the element being ·assessed·." - is that what is meant? These statements look to me like a non-normative description of a subset, not like a normative definition. The only XPath subsets we define are now in sections 3.11 and 3.12, and they are above rather than "below".
