This list of types of claims is used by
CardSpace to help direct the user to a card that supports
the claims that a RP is requesting.
Supported token types. Data expresses which types of
tokens an IP can produce. This generally includes
SAML1.1, but is up to the IP to determine. The list of
supported token types is also used by CardSpace to help
direct the user to a card that can satisfy the request.
Issuer name. This is a particularly important value for
helping CardSpace to guide the user to a card that can
satisfy the current request. It is a logical URI that refers to
the IP. Because the URI is logical (doesn??™t refer to a physical
address), multiple STSs can represent the same IP.
This may be useful for many different reasons, such as
setting up a fallback STS or deploying STSs for different
geographic regions.
A Deeper Look at Information Cards

The information about the user is not in the card. The IP stores
the personal information such as age or Social Security Number,
and thus the information is stored at the STS and requires some
form of authentication to retrieve. The separation of the user??™s
information from the Information Card is shown in Figure 3-7.
