Description
Proposal to revert the Attribute Index handling back to the previous approach (where an Attribute Index not being specified means the Attribute Index is assumed to be 0 in all contexts).
The changes are from the review version of 1.1 only reverting the items related to requiring attribute index to always be specified and defining an index of -1 to have special meaning.
The error conditions for Modify and Delete were also fixed to match the descriptions (the older descriptions were incorrect for KMIP 1.1).
