Do applications on Mac OS X (specifically the MS Office applications, but interested in others as well) generally preserve xattrs (Extended Attributes) on documents when saving them?
For example, if I add an xattr to a file:
xattr -w test "test attribute" mydocument.docx
Then open this in MS Word, make a change, and save, is the attribute maintained? What does
xattr -l mydocument.docx
print after saving?
