The SAML1Base64 attribute encoder encodes a binary valued IdPAttribute as a SAML 1 Attribute via a Base64 encoding. .
Schema Name and Location
This xsi:type is defined by the urn:mace:shibboleth:2.0:resolver schema 3.3, 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:encoder schema , which is located at http://shibboleth.net/schema/idp/shibboleth-attribute-encoder.xsd. This is still supported, but every element or type in the urn:mace:shibboleth:2.0:encoder schema has an identically named version in the urn:mace:shibboleth:2.0:resolver schema.

Notes
The AttributeNamespace XML attribute in SAML 1 is a nasty little piece of work that was badly defined and very inconsistently implemented (often nonsenically) by different implementations of SAML 1. Shibboleth used this attribute in a manner analagous to the SAML 2 NameFormat attribute that took its place, and defaults to using a URI constant we defined in the very earliest releases to signal that the AttributeName would be a URI and stand on its own. You will typically find that other implementations will require you to override this with some value they invent out of whole cloth. No value is right or wrong, it's an unfortunate mistake that just has to be worked around on a case by case basis.
