+ * A TrustSettings Record contains the XML encoding of a CFDictionary. This dictionary
+ * currently contains two name/value pairs:
+ *
+ * key = kTrustRecordVersion, value = SInt32 version number
+ * key = kTrustRecordTrustList, value = CFDictionary
+ *
+ * Each key/value pair of the CFDictionary associated with key kTrustRecordTrustList
+ * consists of:
+ * -- key = the ASCII representation (with alpha characters in upper case) of the
+ * cert's SHA1 digest.
+ * -- value = a CFDictionary representing one cert.
+ *
+ * Key/value pairs in the per-cert dictionary are as follows:
+ *
+ * -- key = kTrustRecordIssuer, value = non-normalized issuer as CFData
+ * -- key = kTrustRecordSerialNumber, value = serial number as CFData
+ * -- key = kTrustRecordModDate, value = CFDateRef of the last modification
+ date of the per-cert entry.
+ * -- key = kTrustRecordTrustSettings, value = array of dictionaries. The
+ * dictionaries are as described in the API in SecUserTrust.h
+ * although we store the values differently (see below).
+ * As written to disk, this key/value is always present although
+ * the usageConstraints array may be empty.
+ *
+ * A usageConstraints dictionary is like so (all elements are optional). These key
+ * strings are defined in SecUserTrust.h.
+ *
+ * key = kSecTrustSettingsPolicy value = policy OID as CFData
+ * key = kSecTrustSettingsApplication value = application as CFData
+ * key = kSecTrustSettingsPolicyString value = CFString, policy-specific
+ * key = kSecTrustSettingsAllowedError value = CFNumber, an SInt32 CSSM_RETURN
+ * key = kSecTrustSettingsResult value = CFNumber, an SInt32 SecTrustSettingsResult
+ * key = kSecTrustSettingsKeyUsage value = CFNumber, an SInt32 key usage
+ * key = kSecTrustSettingsModifyDate value = CFDate, last modification
