Changes for Datatype
Datatype taxonomy is replaced by a datatype content type, to create a new one go to /node/add/datatype. You can specify basic documentation of the datatype and specify enumerated values. A datatype must be placed in a package.

xs:date

This datatype is modeled after the calendar dates defined in Chapter 5.2.1 of ISO (International Organization for Standardization) 8601. Its value space is the set of Gregorian calendar dates as defined by this standard; i.e., a one-day-long period of time. Its lexical space is the ISO 8601 extended format: [-]CCYY-MM-DD[Z|(+|-)hh:mm]

Valid values include: 2001-10-26, 2001-10-26+02:00, 2001-10-26Z, 2001-10-26+00:00, -2001-10-26, or -20000-04-01.

xs:boolean

The datatype xs:boolean has the ·value space· required to support the mathematical concept of binary-valued logic: {true, false}. (http://www.w3.org/TR/xmlschema-2/#boolean)

An instance of a datatype that is defined as boolean can have the following legal literals {true, false, 1, 0}
