For my money, Attach:foo.txt"{md5} {size}" makes the most sense and 
is the most readable.  For naive authors, %size may be confusing 
whereas {size} seems pretty clear. A complete set of file 
attributes[1] would be:

         Attach:foo.txt"{md5} {size} {date}"

I seem to remember that curly braces were difficult to type on German 
keyboards, which may make this a less popular choice in some circles.

Not sure how the MD5 would be created (upon saving the page?, 
uploaded by the user?) because some of the files I have online are 20 
megs, and calculating an MD5 on-the-fly would seem to be a colossal 
waste of cycles.

[1] The complete set that makes sense for a wiki where the file is read only.
