title: Does xs:time default to UTC when time zone is omitted?
body: <p>The <a href="http://www.w3.org/TR/xmlschema-2/" rel="nofollow noreferrer">XML schema spec</a> seems vague on how to interpret an xs:time value when no time zone is specified. (See <a href="http://www.w3.org/TR/xmlschema-2/#time" rel="nofollow noreferrer">section 3.2.8</a>.) Is there a common consensus on this (e.g. UTC or the local time zone)? </p>
