We need additional test cases in unit testing to deal with the fact that we can have custom_analyzers or not.

Actually the existing tests are not failing, which is good, but there is no clue about the expected result if the field is meant to have custom_analyzers

I think we need some unit testing here, this file is already covered so any new method should also be.

I'm not a huge fan of having json_encoded data being set inside XML file, couldn't it be an XML array either ?

By the way, I think the xsd schema should be updated with this new config node probably.
