They can. That doesn't stand in the way of using "/" to separate
the named stream's name from the file (or directory) that
have the attribute.  "Directories may have metadata" pops
up now and then, and the solution is so blindlingly obvious
that nobody sees it.

A file-as-dir can be implemented as a rather normal directory
attached to the file's name.  The stuff inside may
be interpreted as "attributes" or as something more file-like,
such as the often mentioned thumbnails.

What about a directory then?  It _is_ a directory, so it
support named streams already.  They are usually called "files". :-)
So, if you really want a thumb for your directory, just store a
thumb.jpg in it.
