Displaying server-side errors using Kendo Validator

Displaying server-side errors using Kendo Validator

I have a web form that does client validation using Kendo Validator. Once
client validation succeeds the form values are sent to a web service that
does additional validation and either saves the data or sends back a JSON
object of error messages keyed by form field. These field names match the
data-for attributes on the validator elements. Is there a way to display
these errors using Kendo Validator?
I realize you can setup a custom rule to do server-side validation per
field. This is about validating all the fields at once and displaying
multiple errors.
