I've been studying diverse musicXML files with MuseScore and I've found that usually rest notes are easily represented and visible in its musicXML file.
Yet, I found this 'repeated rest' at the start of a song which has particularly intrigued me since I'm using the xml file to build an object for a different software, resulting into a repeated rest which is obviously not desired.
It has a backup value which I couldn't find much information about. I'm obviously not a musician.

The partiture:
What also calls my attention is that the rest note does not have any type value which according to the museScore partiture it should be a half.
Next rest, which is also a rest, has its proper value of a quarter and it's not repeated.
It's important to understand this, otherwise I will not be able to generate the proper algorithm for the time stamps of each note.
