Interface TypeInfo

public interface TypeInfo

The TypeInfo interface represent a type referenced from Element or Attr nodes, specified in the schemas associated with the document. The type is a pair of a namespace URI and name properties, and depends on the document's schema.

If the document's schema is an XML DTD [XML 1.0], the values are computed as follows:

• If this type is referenced from an Attr node, typeNamespace is null and typeName represents the [attribute type] property in the [XML Information set] . If there is no declaration for the attribute, typeName is null.
• If this type is referenced from an Element node, the typeNamespace and typeName are null.

If the document's schema is an XML Schema [XML Schema Part 1] , the values are computed as follows using the post-schema-validation infoset contributions (also called PSVI contributions):

• If the [validity] property exists AND is "invalid" or "notKnown": the {target namespace} and {name} properties of the declared type if available, otherwise null.

  Note: At the time of writing, the XML Schema specification does not require exposing the declared type. Thus, DOM implementations might choose not to provide type information if validity is not valid.

• If the [validity] property exists and is "valid":
  1. If [member type definition] exists:
     1. If {name} is not absent, then expose {name} and {target namespace} properties of the [member type definition] property;
     2. Otherwise, expose the namespace and local name of the corresponding anonymous type name.
  2. If the [type definition] property exists:
     1. If {name} is not absent, then expose {name} and {target namespace} properties of the [type definition] property;
     2. Otherwise, expose the namespace and local name of the corresponding anonymous type name.
  3. If the [member type definition anonymous] exists:
     1. If it is false, then expose [member type definition name] and [member type definition namespace] properties;
     2. Otherwise, expose the namespace and local name of the corresponding anonymous type name.
  4. If the [type definition anonymous] exists:
     1. If it is false, then expose [type definition name] and [type definition namespace] properties;
     2. Otherwise, expose the namespace and local name of the corresponding anonymous type name.

Note: Other schema languages are outside the scope of the W3C and therefore should define how to represent their type systems using TypeInfo.
