Re: 3rd try at Algorithms Section

XML Encryption Algorithms DraftSome comments on the ARCFOUR section (I don't
have any significant comments on the others).

It is correct that a key can only be used once, but there is a rather
unofficial standard to place use an IV (in this case it would likely be
prepended to the ciphertext), and to concatenate this after the key for the
key schedule (easiest reference is CipherSaber). If we do incorporate an IV
we would have to define the length of the IV in some way.

The keysize is unnecessary. The key schedule for ARCFOUR is such that any
key size (up to 2048 bits) is valid, and the method of doing so is well
documented.

These are relatively minor things, and since ARCFOUR is just there as an
example it's debatable whether or not we should actually make these
changes..
