With the following answer: Manifest declared validators are for server-side validation without you having to write any c#, if you require more complex server side validation then you will need to write a c# property editor.
Is it still relevant ? Basically I just want to add a validator in c# and associate it with my custom property editor without creating the property editor in c#
Update: turns out for v11 it is mandatory to have a manifest file regardless of having .cs files for the config for the data editor. Our manifest file was very small as most of our config went into the .cs file
Server side validation for js property editor

I saw this post from 2014: https://our.umbraco.com/forum/umbraco-7/developing-umbraco-7-packages/54788-V7-packagemanifest-validation-array
