Specifies a signing KeyInfo portion of SPSSODescriptor to be used
in Service Provider metadata. This should be an XML portion
which in the simplest case is formatted as shown below:
This fragment should contain a certificate that contains a public
key of a Service Provider in case an idP requires that SAML
requests are signed.
The term "signing certificate" is a misnomer. A signing
certificate in metadata is actually used for signature
verification, not signing. The private signing key is held
securely by the signing party (SP in this case). In a SAML
exchange an SP signs SAML messages with its private key and idP
validates them via a public key embedded in a certificate present
in the SP's metadata XML and vice versa for idP.
