      The SQL/JSON standard borrows its definition for regular expressions
      from the <literal>LIKE_REGEX</literal> operator, which in turn uses the
-     XQuery standard.  PostgreSQL does not currently support the
-     <literal>LIKE_REGEX</literal> operator.  Therefore,
-     the <literal>like_regex</literal> filter is implemented using the
-     POSIX regular expression engine described in
-     <xref linkend="functions-posix-regexp"/>.  This leads to various minor

+     filter is implemented using the POSIX regular expression engine, see
+     <xref linkend="functions-posix-regexp"/>. This leads to various minor
      discrepancies from standard SQL/JSON behavior, which are cataloged in
