Problem with tei:line when serializing B3
Extracted from https://gitlab.gwdg.de/fontane-notizbuecher/SADE/-/commit/f842e8e0d2f164d800900f74991e6e37f4dce7f5#note_144194.
For some reason else if($node/following::*[1][self::tei:lb[@break = "no"]] ...)
returns true()
for tei:line
on surface 57r which results in missing elements. The fix proposed in !66 (merged) solves this, but the reason for this unexpected behaviour is still unclear.
