The TScCertAuthorityInfoAccessExtension class represents the authority information access extension that contains a list of the TScInfoAccess objects, that indicate how to access information and services for the issuer of the certificate.
The following paragraph is taken from RFC 5280, section 188.8.131.52:
"The authority information access extension indicates how to access information and services for the issuer of the certificate in which the extension appears. Information and services may include on-line validation services and CA policy data.
Each entry in the sequence AuthorityInfo describes the format and location of additional information provided by the issuer of the certificate in which this extension appears. The type and format of the information are specified by the accessMethod field; the accessLocation field specifies the location of the information. The retrieval mechanism may be implied by the accessMethod or specified by accessLocation."
