Incorrect markup solutions
    The aria-command-name rule has four markup patterns that fail
    testing criteria:
  
<div role="link" id="empty"></div>
<div role="button" id="alempty" aria-label=""></div>
<div role="menuitem" id="albmissing" aria-labelledby="nonexistent"></div>
<div role="link" id="albempty" aria-labelledby="emptydiv"></div>
<div id="emptydiv"></div>Why it Matters
  Screen reader users are not able to discern the purpose of elements with
  role="link", role="button", or
  role="menuitem" that do not have an accessible name.
Rule Description
ARIA command elements must have discernible text that clearly describes the destination, purpose, function, or action for screen reader users.
The Algorithm (in simple terms)
  Checks all elements with role="link", role="button",
  or role="menuitem" to ensure that they have a discernable,
  accessible name.
