This was originally added to Freeciv upstream in
<http://gna.org/patch/?2011>.
Flag is described as "PD image" in that ticket, but the version of
<http://commons.wikimedia.org/wiki/File:Flag_of_Sikkim_monarchy.svg>
that was current at the time appears to have had a tag
{{self|cc-by-sa-2.5}}. This isn't quite the same as what the SVG
metadata claims, I think; don't know if that makes any difference.

The current version on Commons is described as "This file is ineligible
for copyright and therefore in the public domain because it consists
entirely of information that is common property and contains no original
authorship." So we could use that instead?

This was added upstream under <http://gna.org/patch/?2205>.
The then-current version of the Commons file
<http://commons.wikimedia.org/wiki/File:Banner_of_Saxony_(1%5E1).svg>
was described as "Permission=Own work, all rights released (Public
domain)". The current version is described as being in the public domain
for various being-a-state-symbol sorts of reasons.

If so, it looks like the embedded licence metadata for this file is in
error.
