MSN style files created with help from the Royal National Institute of Blind People (RNIB).
The following rules are useful for any group of related styles, in particular these MSN styles:
XML tags must be specified in the order that MuseScore Studio writes them when saving a style. Each tag must appear zero or one times per file. No duplicate tags are allowed.
All files in the group must contain the same tags. If a tag appears in one file then it must appear in all files. Values within tags do not have to be the be the same in each file.
If a particular value is the same in all files, and it also matches MuseScore Studio's default value for this tag, then the tag should be omitted from all files.
Values that are considered intrinsic to the style (in this case to MSN) should be retained in the style files even if they do happen to match MuseScore Studio's (current) default values.
These rules enable MSN styles to benefit from future improvements to MuseScore Studio's default style values, while also ensuring that users can quickly switch between different MSN styles without leaving any values in place from the previous style.
