Thanks for these pointers.  On the "standards under development"
page[1], I see that ISO/IEC PDTR 19075-6 (SQL/JSON) is at stage 30.60
"Close of voting/ comment period".  But ISO/IEC CD 9075-15
(Multi-Dimensional Arrays) is in stage 30.92 "CD referred back to
Working Group".  Is that how they say "returned with feedback"?
ISO/IEC PDTR 19075-5 (Row Pattern Recognition) has also reached stage
30.60.  Does anyone know what that one is about?  Maybe something like
MATCH_RECOGNIZE in Oracle?
