Issue fixed by removing role="Lbl" from fo:basic-link.

Issue fixed by removing role="Lbl" from fo:basic-link.

It's wrong solution. Lbl added specially in metanorma/metanorma-iso#1003 (comment).

[Intelligent2013]

Issue solved - added internal fo:inline with role Lbl:
<fo:basic-link internal-destination="{$ref_id}" fox:alt-text="footnote {$current_fn_number}">
<fo:inline role="Lbl">
...
</fo:inline>
</fo:basic-link>

Now the tags structure has Link element between Reference and Lbl:

I can't ignore (skip) the Link element.
