The government is only loosely bound by patents and copyrights for
their own use, though if they promulgate a standard for use by the public,
non-governmental users of that standard risk violating the law without
having the protection of sovereign immunity. The NSA resolved this
problem for DSA by repeated use of "Proof by Vigorous Assertion",
which is a less than satisfying rationale.
