Description
Is your feature request related to a problem? Please describe.
Currently there is only one error-property for arrays, which contains errors from the top level of the array as well as all error messages from its items. This makes it difficult to distinguish between the two types of errors in the array-renderer. For example, it´s not possible to ignore the error messages of the items at the top level of the array, like requested in #1760.
Describe the solution you'd like
Only show the toplevel errors of the array in the error property. Additionally add a childError-property, that list all errormessages of the items.
