[MusicXML] How to specify silent slash notes?

Hello all,

I am trying to recreate lead sheets, such as those created by iReal Pro, in
MusicXML.

Here's the demo of my library which converts the thousands of free iReal
Pro lead sheets into MusicXML: https://blog.karimratib.me/demos/musicxml/

My question is about the semantics of the `measure-style > slash` element,
which I use to specify the duration of each chord: does this element imply
that the corresponding slashed notes in the measure should NOT be played?
Otherwise, how can one specify that slashed notes should be kept silent by
the audio player (or replaced with their chord)?

As an example of interpretation of `measure-style > slash` in the wild,
MuseScore does mute any note that appears in a measure containing such an
element.

Thanks,
Karim
