I am posting a new question after having put a few hours into searching for a solution, and reading through Similar questions.
Using NVDA, when the textbox receives focus, the label (Organization) is read, then the aria-describedby content (200 West Street, New York, NY), and then the value (Goldman Sachs):
<label for="organization">Organization</label>
<input type="text" id="organization" value="Goldman Sachs" aria-describedby="organizationLocation" />
<span id="organizationLocation">200 West Street, New York, NY</span>
For obvious reasons, in this case, it is preferred the label to be read first (Organization), then the value (Goldman Sachs), then the aria-describedby content (200 West Street, New York, NY).
I have also attempted referencing the textbox from the aria-describedby attribute, though the value of the textbox (Goldman Sachs) is repeated, being announced once after the label (Organization) and once after organizationLocation:
<label for="organization">Organization</label>
<input type="text" id="organization" value="Goldman Sachs" aria-describedby="organization organizationLocation" />
<span id="organizationLocation">200 West Street, New York, NY</span>
How difficult is it to achieve the desired functionality?
