Task progress information in a structured form. It considers task parts and buckets. It is named "structured" as opposed to single progress counter that has been present in the task since early ages.

Item Summary
Name	Type	Multiplicity	Description
currentPartUri	property anyURI	[0,1]	Current part URI.
currentPartNumber	property int	[0,1]	Current part number, starting at 1.
expectedParts	property int	[0,1]	How many parts are in this physical task?
part	container TaskPartProgressType	[0,-1]	Progress in individual parts.

- currentPartUri
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Current part URI.
- currentPartNumber
  
  Flags: RAM,runtime
  
  Multiplicity: [0,1]
  
  Current part number, starting at 1. The numbering is relative to the parts processed by given physical task. An example: for simple reconciliation tasks there are parts 1, 2, and 3. For partitioned reconciliation task, i.e. such task that individual parts run in separate physical tasks, each task structured progress has only a single part, numbered 1.
