Add new codes to mantis issue and I will raise with UA WG.

Discussed in WG:
These codes do not belong as StatusCodes because the information does not change frequently on a value by value.
This use case is best resolved by using the existing SemanticChange bit + property indicating the reset cycle and last reset time.

Please confirm my intrepretation of your suggestion:

We use the SemanticChange bit (14) of the StatusCode to indicate this (as documented in Table 176 of Part 4):

SemanticsChanged

14:14

Indicates that the semantics of the associated data value have changed. Clients should not process the data value until they re-read the metadata associated with the Variable. Servers should set this bit if the metadata has changed in way that could cause application errors if the Client does not re-read the metadata. For example, a change to the engineering units could create problems if the Client uses the value to perform calculations.
Part 8 defines the conditions where a Server shall set this bit for a DA Variable. Other specifications may define additional conditions. A Server may define other conditions that cause this bit to be set.

This bit has meaning only for StatusCodes returned as part of a data change Notification or the HistoryRead. StatusCodes used in other contexts shall always set this bit to zero.

Randy, please verify solution.

Added the following to the section on streaming.

MTConnect supports data items that provide statistical values for various numeric quantities. The statistics can be reset at arbitrary points in time by indicating the reason for the reset in the attribute \mtmodel{resetTriggered} in the streaming data. The client application is then aware of the occurrence of the reset and why it occurred.

When the \mtmodel{resetTriggered} attribute is give, the property in the \mtmodel{MTNumericDataItemType}, this is included in all numeric data items, will set the \mtmodel{MTResetTriggeredReason} to the enumerated value. The update will also set the \uamodel{SemanticsChanged}, bit 14 of the \uamodel{StatusCode} (see \cite{UAPart4} \textit{Section 7.34 StatusCode}, associated with the data update to indicate to the client application that it should interrogate the \mtmodel{MTResetTriggeredReason} property.

Changed to SemanticsChanged bit in the model and in the section on streaming.

Included in final 2.0 release
