You could argue that all filesystem eas are really just files within the
file, with a slightly different API for reading/writing them.
In the changeset, you would want to represent the differences between
two versions of a file. You could simply store the new attribute with
the file, if they are small it would actually take less space than a
real diff.
For larger eas though, you might want to be able to store some diff.
