It sounds like a small thing, but it can severely impact scripting and
labeling. For instance, you explicitly label a form field using a matching
for and id attribute, but if duplicate ids exist the wrong label can be
announced. The same is true when implementing ARIA, where many features are
bound using the id attributes to identify node relationships, labels, and
instructional text.
