At the moment it is only possible to implement custom rules for PL/SQL in XPath 1.0.
XPath 1.0 is quite limited (e.g. no support for regular expressions), so developing a custom rule can be a pain.
Would it perhaps be possible to enable the development of custom rules in Java for PL/SQL code?
It would be important to me that issues of these custom rules are also found with SonarLint.
