IBISQ Embedded Value Characters To Flag Special Meanings

[Garth Braithwaite]

Need more visibility to handle the various special cases for SAS/IBISQ values. It is a bad practice to embed characters into numeric values to be used as some type of flag. This quick and dirty solution is "easy" at first but becomes costly as needs change and others components try to consume the data.

To code correctly what is needed is to have IBISQ return the appropriate XML element(s) that defines the special characteristics of a data value. For example <SUPPRESSED_VALUE/>, <INSUFFICIENT_DATA/>, <NO_DATA_EXISTS/>, <UNSTABLE_VALUE/> etc.
