With Tagged PDF on, a paragraph in a language other than the document's
gets /Lang on its structure element. What is anchored in the paragraph
is tagged inside that same element and inherits the attribute, so a
frame's text and its description would be declared the paragraph's
language.
0d2d9e656d87647f904f1a463ed9b879c2bfb10c (tdf#163272 sw: give a
paragraph its own /Lang, 2026-09-21) avoided that by putting no /Lang on
such a paragraph, on a check of one node of a text frame that can cover
several. Its text still carried the language, on a Span, while what was
anchored in it specified none and inherited the document's. In a German
document that declared a shape's English text German. See

The paragraph specifies its own language now, and a frame anchored in it
no longer inherits it. A Figure, a Formula and a frame's Division
specify the document's where the paragraph's differs, which is what the
frame's own paragraphs are measured against. A drawing shape's text is
tagged by drawinglayer, which takes the locale of the drawn portions and
specifies it where they agree; such a shape is nested in its anchor
paragraph in Writer and in no such paragraph elsewhere, so there is
nothing to compare against.
A drawing shape's own element specifies the document's language too. svx
anchors it under the anchor paragraph, drawinglayer opens it there, and
it carries the shape's title and description. Without the attribute, a
described shape in a paragraph that specifies one would have its
description declared the paragraph's language, and its text likewise
where the portions disagree.
testParagraphLanguage compared a structure type against a language and
quoted no text, so nothing identified the words affected. It lists every
element holding text or a description now, against the language it
specifies, an entry reading "P de-DE: Ein deutscher Absatz mit einem
Bild."; one specifying none is listed without a language, so correct
inheritance is asserted too. PDFiumPageObject gained getMarkedContentID
to join a page object's text to its element.
