+
+Dynamic Aria labels like used in generic components are also possible! 
+
+For usage only the `attr.` tag prefix must be added like in following code example:
+
+```
+<button
+      mat-button
+      attr.aria-labelledby="{{ ariaPrefix + 'cancel' }}"
+...
+...
+<div id="{{ ariaPrefix + 'cancel'}}">{{ buttonsLabelSection + '.cancel-description' | translate }}</div>
+```
