Hi Andrii Poliakov,
After reviewing the elements and our use of them, I can provide general descriptions that should allow you to use them. We don't have public schemas as found in ISO 29500 A.6.6 for these specific elements because they are not used directly in the WordprocessingML found in Word file format (.docx) packages. Here are the definitions for the element you list:
b:Hyphens - the set of characters that represent hyphens for the locale id specified in the b:Local element's LCID attribute.
b:Date/b:DMY - is the string representing the day, month and year, each value separated by spaces like this: "13 August 2025"
b:MainAuthor/b:FL - is the string representing the first and last name of the main author (in that order) separated by a space like this: "Tom Jebo"
b:MainAuthor/b:LF - is the string representing the last and first name of the main author (in that order) separated by ", " like this: "Jebo, Tom"
b:SecondaryAuthors/b:FM - is the string representing the first and middle name of the secondary author separated by a space like this: "Tom Cameron"
b:GeneralClose - is the character representing the close parenthesis or ")"
Best regards,
Tom Jebo
