If this is the wrong list to send this to, my apologies, please let me know where to go.
I've used nxml-mode for a long time. When typing in an xml attribute and using completion, emacs would respond by completing the attribute and also adding =" to allow me to immediately type the value of the xml attribute. I recently upgraded to emacs 26, and it now only completes the attribute hame. The original completion behavior (adding =") is described in the manual at <https://www.gnu.org/software/emacs/manual/html_node/nxml-mode/Completion.html> . To replicate - open an html file in nxml mode - ensure it's tied to the html schema file - type "<html xmln" - trigger completion (C-M-i, or whatever calls completion-at-point) expected behavior (pre emacs 26) line shows: <html xmlns=" actual behavior, line shows <html xmlns Martin Fowler http://martinfowler.com
