 The \refapi{PMIx_Query_info} operation is expected to be called between initialization (e.g., \refapi{PMIx_Init}) and finalization (e.g., \refapi{PMIx_Finalize}) with the exeption of calling the blocking query \ac{API} exclusively with the following set of query attributes:
 \begin{compactitem}
-\item \refattr{PMIX_QUERY_ABI_VERSION}
+\item \refattr{PMIX_QUERY_STABLE_ABI_VERSION}
+\item \refattr{PMIX_QUERY_PROVISIONAL_ABI_VERSION}
 \end{compactitem}
 If this operation is called exclusively with one or more of those attributes then the result is computed locally to the \ac{PMIx} implementation and returns the associated value.
