• ##any - attributes from any namespace is allowed (this is default)
• ##other - attributes from any namespace that is not the namespace of the parent element can be present
• ##local - attributes must come from no namespace
• ##targetNamespace - attributes from the namespace of the parent element can be present
• List of {URI references of namespaces, ##targetNamespace, ##local} - attributes from a space-delimited list of the namespaces can be present

• strict - the XML processor must obtain the schema for the required namespaces and validate the elements (this is default)
• lax - same as strict but; if the schema cannot be obtained, no errors will occur
• skip - The XML processor does not attempt to validate any elements from the specified namespaces
