Attribute Value: "service"

Description: rel="service" indicates a URI that can be used to
retrieve an Atom Publishing Protocol Service Document as defined
by RFC 5023.

Display Characteristics: Support for rel="service" links will vary
across user agent implementations. The link relation is intended to
provide user agents with a means of auto-discovering service endpoints
so that basic configuration actions can be performed automatically with
minimal user input. User agents may or may not present the link to end
users.

Security Considerations:

The link element is subject to tampering and observation, as is the
linked resource. For that reason, implementations should clearly signal
the level trust and privacy a linked resource provides. If present,
digital signatures provide authentication, message integrity, and
non-repudiation with proof of origin. Encryption provides data
confidentiality. Implementations should also consider the level of
confidentiality and message integrity provided by the transport used to
reach the payment resource.
