o Add the "PART::scheme" attribute that returns the name of the

   underlying partitioning scheme.
o  Put the start and end of the partition in the XML configuration.
   The start and end are the LBAs of the first and last sector
   (resp.) of the partition. They are currently identical to the
   offset and size attributes, which describe the partition as an
   offset and size in bytes, but may not in the future. The start
   and end will be used for the logical partition boundaries and
   may include metadata. The offset and size will always represent
   the useful storage space within the partition. Typically these
   two notions are the same, but for logical partitions in an
   extended partition, the EBR is more naturally treated as being
   part of the partition.
