Verification Failure: Form Annotation does not define the TU attribute

Issue

After running a verification, you received the following failure: "The Form Annotation does not define the TU attribute."

Causes

All form tags require tooltips (TU) because this is the text that assistive technology announces to identify the purpose of the forms.  Without it, an assistive technology user may only be told "Edit" or "Checkbox" etc., without knowing what information is being requested.

Resolution Steps

If you run a verification and receive a failed result for a form annotation that lacks a tooltip:

1. Open the fix wizard, and the text that is in the Form tag with the Annotation will automatically be populated in the textbox.
2. Edit the tooltip as needed or decide to use the text as it appears in the Fix Wizard.
3. Press Finish.

Note: If there are multiple failures due to many form Annotations not having tooltips:

1.  Check the box in the lower-left corner to “Apply fix to all similar issues.” 
2. Use default values – the “default” is to use the text that is in the Form tag with the Annotation.  

Note:  If there are form fields in the document that do not have text with them, then there will not be any text available to automatically populate for the tooltip. 

Note: Tooltips for specifically formatted form fields present another unique challenge.  If, for example, the user is asked to enter a date in a form, and the properties of that date field require the answer to be entered in a two-digit month, two-digit, day, four-digit year format, then include a description of this formatting requirement in the tooltip.
