   /**
    * A Validity object contains all information to check if a Source object is
    * still valid.
  + * There are two possibilities: The validity object has all information
  + * to check by itself how long it is valid (e.g. given an expires date).
  + * The other possibility needs another (newer) validity object to compare
  + * agains (e.g. to test a last modification date).
  + * To avoid testing, what the actual implementation of the validity object
  + * supports, the invocation order is to first call isValid() and only if
  + * this results in <code>false</code>, then to call isValid(SourceValidity).
  + * But remember to call the second isValid(SourceValidity) when <code>false</code>
  + * is returned by the first invocation!
