The WD defines a mapping between Information Items (InfoItems) and syntax data model nodes. Namespace InfoItems have no mapping to data model nodes. You note that the Element and Attribute InfoItems do have mappings however only Element has a property that takes an Namespace InfoItem value - [in-scope namespaces], and we do not use that property as declared in http://www.w3.org/TR/rdf-syntax-grammar/#section-Data-Model The only InfoItem properties related to namespaces that are used are [namespace name] which is a URI string, not a Namespace InfoItem. We don't use the [prefix] InfoItem property anywhere. Would it be better to replace "Not used" with "No mapping made to data model nodes" ? Thanks for the feedback Dave
