Does MuseScore have xml files available in addition to pdf files?

Hi,

I am considering a MuseScore subscription, but I need access to xml files so I can more quickly do
arrangements for my band. Several questions, please:

Does MuseScore have xml files available for most if not all of its charts?

When searching for a chart; just as an example, Satin Doll, how can I tell if a search result has both pdf and xml available?

Is there a way I can contact MuseScore directly with my questions? I looked under the Support tab on the webpage, which is where I would expect to find the Contact link, but it was not there.

Many thanks,
Lou
