A code or name for the property as used by the data
provider. This value can come from a controlled list of terms or be
an uncontrolled text string. The value would be commonly used to
label a column of a log sheet or provide other local meaning to the
property. The value of mnemonic should be unique for all of the
properties included in the dataValue block transmitted as part of
this measurement.
