The phrase "any characters outside the UTF-8 character set" appears many times, and I'm afraid it doesn't really make any sense. What you probably want to do is define a term somewhere in the document to formally specify "Those Things That Must Be Base-64 Encoded". I would recommend something like: "For the purposes of this document, we define 'unprintable' to mean a string of octets that: (a) contains an octet with a value in the range of 0 to 31, inclusive; (b) contains an octet with a value of 127; or (c) contains any series of octets greater than or equal to 128 which do not form a valid UTF-8 sequence, as specified by [UNICODE]." Then, your statements become far simpler; for example: "The Value field for the optional element being logged MUST be Base64 encoded if it is unprintable." And: "For an optionally logged message body (Tag=01) the BEB is set according to whether the message body is unprintable." And: "When optionally logging an entire SIP message (Tag=02) the BEB is set according to whether the message body portion is unprintable." You get the idea. /a P.S. The above definition would require adding a reference for [UNICODE], like so: [UNICODE] The Unicode Consortium. The Unicode Standard, Version 6.2.0, (Mountain View, CA: The Unicode Consortium, 2012. ISBN 978-1-936213-07-8) <http://www.unicode.org/versions/Unicode6.2.0/>
