Node

Key referring to an arcrole type definition

A (standard or non-standard) label or reference resource

An element label, named label:label (and not any resource in that substitution group).

An element reference, named reference:reference (and not any resource in that substitution group).

Key referring to a global element declaration. Typically the global element declaration is for a concept (that is, item or tuple), but this is only known if we have enough context to determine the substitution group inheritance hierarchy. It could also be a global element declaration for a typed dimension member.

Key referring to a named type definition.

Any other LocatorNode. It contains an ElementKey, and therefore carries no semantics in isolation. It is assumed that the element key is unique in the entire document collection.

An example is a locator to an enumeration value, assuming the enumeration value has an ID and the element key is unique across the taxonomy document collection.

Another example is a locator to a ResourceNode, using a ResourceKey as element key.

Any other NonStandardDocumentationResource. Should hardly, if ever, be encountered.

Any other ResourceNode. For example, table content like table, ruleNode, or formula content like formula:valueAssertion, or a custom resource node, such as sbr:linkroleOrder in Dutch taxonomies.

It contains an optional element key, and therefore carries no semantics in isolation. It is assumed that the element key, if present, is unique in the entire document collection.

Key referring to a role type definition
