matthew roth updated FOP-3322:
------------------------------
Description:
When the following is enabled
{code:xml}<accessibility>true</accessibility>
<pdf-ua-mode>PDF/UA-1</pdf-ua-mode>
{code}
{{fox:alt-text }} on {{ fo:basic-link}} with {{ internal-destination}} sets the
{{/Alt}} attribute on the {{/Link}} structure element but does *not* set the
{{/Contents}}
key on the {{PDLinkAnnot}} annotation dictionary.
ISO 14289-1 (PDF/UA-1) §7.18.5 requires:
> Links shall contain an alternate description via their Contents key as
> described
> in ISO 32000-1:2008, 14.9.3.
External-destination links appear to get {{/Contents}} set correctly; only
internal-destination links are affected.
A fix should propagate {{fox:alt-text}} to the {{/Contents}} entry of the
annotation
dictionary for both link types.

the
`/Alt` attribute on the `/Link` structure element but does **not** set the
`/Contents`
key on the `PDLinkAnnot` annotation dictionary.
