There is an improvement: now the tags are identified as <Figure> and <Formula>! But still the figures label={this is a cow} is missing.
Sorry, Steffen, I thought I explained this in a previous message. Alternative text is missing from \externalfigure, because this is the generated PDF object: 17 0 obj << /K [ << /Alt <FEFF0063006F0077> /MCID 1 /Pg 1 0 R /Type /MCR >> ] /P 15 0 R /Pg 1 0 R /S /image
endobj
But it should read: 17 0 obj << /K [ << /MCID 1 /Pg 1 0 R /Type /MCR >> ] /Alt <FEFF0063006F0077> /P 15 0 R /Pg 1 0 R /S /image
endobj
All I know is that it has to be fixed in lpdf-tag.lmt, but I don’t know how to fix it. It is the same for alternative texts in formulas for PDF/UA-1.

Many thanks for that, but https://www.ngpdf.com/ also shows properties for structure elements. I hope it is clearer now, Pablo
