For those playing along at home who are curious:

# apt install xattr

$ wget https://www.debian.org/

$ xattr -l index.html
user.xdg.origin.url: https://www.debian.org/

Some notes:

* wget in stretch doesn't set xattrs (but the version in sid does)

* chromium doesn't set xattrs if you "File→Save" but does if the file type 
is downloaded.

* I wasn't successful in doing this on a tmpfs - perhaps there are 
additional runes to add to the mount options that would make that possible.

* getfattr from the attr package also works
