The Simple attribute definition copies an input attribute to an output attribute. Typically this is used to 'expose' attributes which are sourced from a DataConnector, turning them from internal data into "real" attribute objects.
V3.4+: Configuring this definition typically requires adding an <InputAttributeDefinition> element, and adding one or more <AttributeEncoder> elements.
V3.0 - V3.3: Configuring this definition typically requires setting the sourceAttributeID attribute, adding a <Dependency> element, and adding one or more <AttributeEncoder> elements.
Schema Name and Location
This xsi:type is defined by in the urn:mace:shibboleth:2.0:resolver schema 3 namespace 3.3, the schema for which is located at http://shibboleth.net/schema/idp/shibboleth-attribute-resolver.xsd.
Prior to V3.3, supplied plugins were defined by a schema type (xsi: type ) in the urn:mace:shibboleth:2.0:resolver:ad namespace, the schema for which is located at http://shibboleth.net/schema/idp/shibboleth-attribute-resolver-ad.xsd. This is still supported, but every element or type in the urn:mace:shibboleth:2.0:resolver:ad deprecated namespace has an equivalently named (but not necessarily identical) version in the urn:mace:shibboleth:2.0:resolver namespace. The use of the urn:mace:shibboleth:2.0:resolver namespace also allows a relaxation of the ordering requirements of child elements to reduce strictness.
