1. Formatting lost in section 2.5 on attributes in a message.
2. OID in appendix A for md5 has a pair of "=" that should be spaces.
3. Appendix A - rsaEncryption OID has the final digit commented out -
ditto for md2WithRSAEncryption, md5WithRSAEncryption,
sha-1WithRSAEncryption and signingTime.
4. Section 2.2 - The NOTE: does not make sense anymore. Please remove.
5. Section 2.4.1 - I can't get the first sentence to parse well.
First, I think that it's sense needs to be change to say this is true
for MIME content, not for general content.
