In the SQL Standards session at the Unconference, I found out that the
committee produced this technical report in 2011:
https://www.iso.org/standard/41528.html "XQuery Regular Expression
Support in SQL"; it furthers our lack of support for XQuery in our
implementation SQL/XML. That content is probably relevant for this
topic, even if we cannot do much about it.
