The presence of the HeaderNotice element in a .REQ file generates accessibility tags at the appropriate location in the PDF tag tree structure based on the existence of the attributes FirstPage, MiddlePages, LastPage, OnlyPage and the attribute value set to Yes.
For example, if the
HeaderNotice element exists with the
FirstPage=
Yes attribute authored, accessibility tags generate for the HeaderNotice contents and are placed in the tag tree structure after the Prolog Document Title tag and before the first page contents tags so that it is read in order similar to that of the physical PDF content.
Note: When using the MiddlePage=Yes attribute, if there are more than three pages generated, only the first middle page will include header notice tags in the tagtree structure.
