Add ng-class on main element?

[danhodkinson]

on the target element such as:
<span class="hardwareBlock__name" ng-click="editText()" inline-edit="inlineEdit[1].model" inline-edit-placeholder="{{inlineEdit[1].placeholder}}" inline-edit-message="{{inlineEdit[1].message()}}" inline-edit-on-blur="cancel" inline-edit-validation="inlineEdit[1].validator(newValue)"></span>

Is it possible to add an ng-class on to this so that when i have a validation error or success i can add a class which will allow me to style siblings of the editable fields (e.g. labels)
