You want all of this in one extended attribute? Even assuming no
overhead for NSArray or NSStrings, wouldn't 100 chars/tag * 100 tags
already be about 2-3 times the maximum amount of storage currently
allowed in one generic extended attribute? As I understand the maximum
is roughly 4K, with the ResourceFork being a special case clearly.
