  attribute provided in ContextAttributes is already present in the existing
  context, the existing value is replaced by the new value. If an attribute
  provided in ContextAttributes is not present in the existing context, then
  the new attribute is added. Attribute values are never deleted from the
  existing context.

  condition. The value CSSM_OK indicates success. All other values represent
  an error condition.
