FillableField and
FillableCheckbox elements create an AcroForm field or AcroForm checkbox object respectively. To comply with accessibility requirements, the ToolTip property for these AcroForm fields is populated with the ToolTip element value authored.
Note: If the ToolTip element is not authored, the FieldName element value authored is used to populate the ToolTip property as it is required for accessibility checker rules.
When producing a Tagged PDF (see
Creating a Tagged PDF) that includes FillableField/FillableCheckbox elements, a <Form> tag is placed in the tag tree in context to where they are located in the content for logical reader order.
Note: The Accessibility Checker results in a Page Content/Character Encoding failure for selected Fillable Checkboxes. This is an Acrobat glitch and the error is inaccurate and does not affect accessibility in any way. To bypass these errors, the accessibility checker options may be modified by selecting the Category ‘Page Content’ and deselecting option ‘Reliable character encoding is provided’.
