> fox:alt-text not written to /Contents on internal link annotations
> ------------------------------------------------------------------
>
> Key: FOP-3322
> URL: https://issues.apache.org/jira/browse/FOP-3322
> Project: FOP
> Issue Type: Bug
> Affects Versions: 2.11
> Environment: - Linux
> - Apache FOP 2.11
> - `<accessibility>true</accessibility>`
> - `<pdf-ua-mode>PDF/UA-1</pdf-ua-mode>`
> - Validated with veraPDF 1.30.1, PDF/UA-1 profile
> Reporter: matthew roth
> Priority: Major
> Labels: Accessibility
> Fix For: main
>
> Attachments: fop.xml, minimal-links-1.pdf,
> minimal-links-a11y-ua1-1.xml, minimal-links.fo
>
>
> When `<accessibility>true</accessibility>` and
> `<pdf-ua-mode>PDF/UA-1</pdf-ua-mode>`
> are enabled, `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.
