        "(Form) A widget annotation representing an interactive form field (see 12.7, “Interactive Forms”). If the element contains a Role attribute, it may contain content items that represent the value of the (non-interactive) form field. If the element omits a Role attribute (see Table 348), it has only one child: an object reference (see 14.7.4.3, “PDF Objects as Content Items”) identifying the widget annotation. The annotations’ appearance stream (see 12.5.5, “Appearance Streams”) describes the appearance of the form element."
