Syntax of SUBSTRING( ... SIMILAR ...) in FB3, FB4

 Description  « Hide
The examples in README.substring_similar.txt are correct, like
substring('abcabc' similar 'a#"bcab#"c' escape '#')

But the syntax description in this document is wrong:
  <regular expression substring> ::= SUBSTRING(<value> FROM <similar pattern> ESCAPE <escape character>)

Also the syntax in FB3 Release Notes is wrong
  SUBSTRING(<string> [NOT] SIMILAR TO <pattern> ESCAPE <char>)
(both NOT and TO)
