save_musicxml() does not include working title in exported file

[grundton]

Hi everyone!

I am using partitura to create and export algorithmically generated scores.
I wanted to include a title, but whatever I tried, I a title would not appear in the exported file.

I then tried the following, where "BeetAnGeSample.musicxml" is a file that contains a work-title field:

import partitura as pt

score_beethoven = pt.load_musicxml("BeetAnGeSample.musicxml")

print(score_beethoven.work_title)

pt.save_musicxml(score_beethoven, out="beet.musicxml")

The print(score_beethoven.work_title) command showed 'An die ferne Geliebte (Page 1)', which means that the title is read into partitura, but save_musicxml() created an musicxml file WITHOUT a work-title field.

I went through the docs to find out whether this is intended behaviour but I did not find an answer.

I hope you could tell me, whether this behaviour is intended, if I did something wrong and perhaps provide me with a minimum working example or work-around of how I can include a title in a musicXML export .

Best,

Tim
