Exporting a document to PDF/UA-2 produced a file that fails
ISO 14289-2 clause 8.8, once per outline item and internal link.
veraPDF reports
Destination in Outline item, OpenAction or Link annotation is not
a structure destination
The destination named the page and an area on it, and that is all:
what was linked to could only be worked out by looking at what the
layout had put at that position.
A destination for a link or an outline item is now written as a GoTo
action carrying a structure destination beside the page one
(ISO 32000-2 12.3.2.3):
/A<</Type/Action/S/GoTo/D[<page> 0 R/XYZ ...]/SD[<elem> 0 R/XYZ ...]>>
sw creates a destination before its target is tagged, so the node is
remembered while the cursor is on it, and matched against the tags in
the pass that already runs after the last page. Creating one and
remembering its node is a single call now, which every destination a
link or an outline item points at goes through: bibliography entries
and links in the text of a shape are named as well.
The cursor is not always on the target: a jump that selects a frame
or a drawing object, and one that finds nothing, move it nowhere, and
where it was left standing on the link, that link's own element must
not become the target. The pass over a shape's links can instead
start with the cursor on the target already, where a jump that did
reach it shows no move either, so there the mark names its own node.
Those keep writing /Dest, as do a target that was never tagged and
one whose element was never emitted.
The element carries its role and its content, not a name of its own:
a heading becomes /S/H1 with no /Alt or /T. veraPDF does not check
what a structure destination points at, so the test does.
