Hi Mario,
In printed music, a double sharp can be represented two different ways:
1) A single symbol that looks like an x. This is the most common way, and is represented by the double-sharp value in MusicXML.
2) Two sharp (#) symbols. This is a less common way typically used in older editions of older music, and is represented by the sharp-sharp value in MusicXML.
Double flats are only represented with two flat (b) symbols, so there is only the flat-flat value in MusicXML.
I would expect that Braille or talking music would not make the distinction between MusicXML's double-sharp and sharp-sharp values. I would recommend writing double sharps using double-sharp, and reading double-sharp and sharp-sharp as synonyms.
Best regards,

Hi.
Looking at the valid accidental names in MusicXML XSD, I am confused:
<xs:enumeration value="double-sharp"/>
<xs:enumeration value="sharp-sharp"/>
<xs:enumeration value="flat-flat"/>
Is sharp-sharp a synonym for double-sharp? If so, why is there no double-flat? And if not, what is the difference between sharp-sharp and double-sharp, and again, why is there no complementary double-flat.
