Many people felt that to insist on a timezone made extra work for them because they always referred to a single local timezone. Making values partially ordered creates other headaches and I would not recommend making dates without timezones partially ordered.

Hi, I feel uneasy about the comparison of two xs:dateTime (or xs:date) values when none of them have a timezone. Doing so, we acknowledge that the timezone -which is undetermined when not specified- is identical all over an instance document and (still more controversial IMO) between the schemas and the instance documents. It's kind of implying the notion of a "user's timezone" which I haven't found explicitely described in the recommendation and which we can specify neither in a schema nor in an instance document. Wouldn't be safer to recognize that, like it is the case when a datetime with timezone is compared to a datetime without timezone, there is only a partial order when two datetimes without timezones are compared?
