[DDI-SRG] inline ncube, proposal for sparse matrice

[Joachim Wackerow]

Currently we can represent only a complete ncube with the inline ncube 
module. I see the requirement to represent also sparse matrices as a 
inline ncube.

See below my proposal. Please note the addition of the attribute 
"sparse" at the NCubeInstance and the additional Dimension elements 
inside of the MeasureValue.
With a value sparse="false" the Dimension elements inside of 
MeasureValue would be omitted, which is already the case in the current 
inline module.

Attached is a valid  DDI instance with a complete inline ncube.

Other ideas?
