@@ -10,21 +10,23 @@ There are numerous problems within the standard ZTC 1.3.
For some of these problems, we have posted issues on [Github for ZGW](https://github.com/VNG-Realisatie/gemma-zaken/issues).
In the table below we list the Github issues and indicate how various Roxit components (should) deal with them.
