[Os-project-managers] Consent agenda items: Sparse objects inOSgL.xsd

[Jun Ma]

Sorry for the delay. I have studied the OSgL. Below are the answers.
> Consent agenda item 1: remove
> LinearConstraintCoefficientsNonNegativeIntVector. It is not and will
> never be used.
 consent.

> Consent agenda item 2: remove
> NonNegativeIntVectorWithValueAndDescriptionAttribute and
> NegativeIntVectorWithValueAndDescriptionAttribute. It is easy to add
> the attributes in a different way.
consent.

> Consent agenda item 3: Change SparseVector to:
> attribute "numberOfValues"
> nonnegative integer array <indices> (with mult and incr but *no*
> separate numberOf...)
> double array <values> (with "mult" only, no incr, no separate numberOf...)
> A definition and a use case are given in Appendix A and Appendix B,
> respectively.
consent.
I have some reservation over this. But I don't have a strong opinion on 
either the old way and this new way.

> Consent agenda item 4: Use new SparseVector in <matrices> (other than
> <linearConstraintMatrix>)

consent.
