Notes
-----
The length of this vector can never 2.  It is either 0, if the vector is empty, or >=4, if the vector has at least one extension.  Nothing elsewhere in the spec requires a non-zero number of extensions here, so this syntax should allow a zero-length vector.

Paul Wouters (AD): Richard meant the diff to be the fix, not the original/corrected text. The diff is not in the RFC itself. There are two places in the mentioned sections that need this one liner fix.
