• hyperlinks: for cells, ranges, cols, rows
• range: copy
• row: copy
• col: copy
• cell: comments
• cell: formulas
• cell: typed getter/setter for values
• other: conditional formatting
• other: rich texts
• other: drawing
• other: more optimization
• other: more tests

Contribution

• To prevent mess, sources have strict separation of markup and functionality. Document that describes OOXML is quite huge (about 6K pages), but the same time - functionality is not.
• All markup resides inside of 'ml' folders, only marshal/unmarshal is allowed here, no any functionality.
• Not every 'ml object' has related 'functional object' and vice versa.
• If you want some functionality, then wrap 'ml object' and do what you want.

OOXML edition

XML is compliant with part 1 of the 5th edition of the ECMA-376 Standard for Office Open XML
