It is important to note that since OpenDocument is an Open Standard file format, there is no need for everyone to use the same program to read and write OpenDocument files; someone with a disability is free to use whatever program works best for them.
值得注意的是，因為 OpenDocument 是一種標準檔案格式，所以並不需要每個人都用相同的程式去讀寫OpenDocument的檔案；每個人都可以自由使用最適合它們的軟體去讀寫這種檔案。
