In an environment where use is made of a character repertoire based on ISO/IEC 646, "hyphen" and "minus" are both mapped onto "hyphen-minus". Representations with a "plus-minus" shall only be used in such environment if the interchange repertoire includes "plus-minus"
Truncated representation, as specified in [ISO.8601.2000], Sections 5.2.1.3 d), e), and f), is permitted., although removed in ISO 8601:2004

If the time in UTC is known, but the offset to local time is unknown, this can be represented with an offset of "-00:00". This differs semantically from an offset of "Z" or "+00:00", which imply that UTC is the preferred reference point for the specified time. RFC2822 [IMAIL-UPDATE] describes a similar convention for email
NOTE: ISO 8601 defines date and time separated by "T". Applications using this syntax may choose, for the sake of readability, to specify a full-date and full-time separated by (say) a space character.
