Accessibility
From Documentation
The za11y module (currently preview) enables developers to create WCAG 2 compliant applications. Key features include keyboard interaction and screen reader support. An accessibility-ready theme (wcag*) should be used along with the module to deliver sufficient contrast.
Specify ARIA Attributes
You can specify arbitrary ARIA attribute on a component with namespace "client/attribute". For example you can add an aria-label like
<zk xmlns:ca="client/attribute">
<div ca:aria-hidden="true"/>
<textbox ca:aria-label="${field}"/>
</zk>
