Use the title attribute to label form controls when the visual design cannot accommodate the label (for example, if there is no text on the screen that can be identified as a label) or where it might be confusing to display a label. User agents, including assistive technology, can speak the title attribute. Therefore the “title” attribute should not be empty.
Engine scans input, textarea, button and select elements for empty title attribute
Users who use assistive tools, such as screen readers rely on a descriptive information to detect the content
<label for="searchTerm">Search for:</label>
<input id="id_example_searchTerm" type="text" size="30" value="" name="searchTerm">
<select title="Search in" id="id_example_scope">
