git support for "xattrs" (extended filesystem attributes)?

Hi everyone :)

I'm evaluating and testing extended attributes (xattrs) for professional archival collection use. I couldn't find any proper documentation/information on how (well) git supports including xattrs in version control.

I assume behavior may be similar to any other property-change of files/folders? Would it be possible to have bit-proof preservation of all xattrs? (even larger ones).

I'm grateful for any insights, pointers or comments. :D

Thanks in advance, Peter B.
