/*
 * This represents a set of attributes from the secrets API. We
 * call them 'fields' here, so they don't get mixed up with the
 * PKCS#11 API's notion of attributes.
 *
 * Each field has a name, and a string value.
 *
 * Previous versions of mate-keyring had the notion of attributes
 * that were integers. In this version everything is a string.
 *
 * Compatibility attributes start with gkr:compat:
 *
 * gkr:compat:uint32:xxxx  The presence of this attribute means that
 * the xxxx attribute is a uint32 in older versions of mate-keyring.
 * The value of this attribute is insignificant.
 *
 * gkr:compat:hashed:xxxx  This attribute contains a hashed version
 * of xxxx.
