Error message mechanism with multiple labels
When multiple <label> elements are associated with a label-able element, the accessible name should be the product of the text content of each of the labels concatenated by DOM source order and space separated.
All associated label elements are used, in DOM order, for name calculation.
Only the first associated label element that is encountered in the DOM is used for name calculation.
