ERS RFC 4998 question



Hi,

In a recent discussion I was asked to explain how the timestamp
in an ERS ArchiveTimeStamp is created.
The text does not seem to be clear, point 5 on page 11:

5 Obtain a timestamp for this root hash value.
Does it mean that the hash value will be presented directly
or a hash of that value.

If it is presented directly, what has to be done for the root
when the algorithm supported by a TSA and the digestAlgorithm
indicated in the ArchiveTimeStamp are not the same?

TIA for any info
/P
