Extension of a Decimal value for use with monetary values where a currency code needs to
be specified.
The currency code is actually metadata about the value so, in line with good XML practice, the Currency Code is declared as an XML-Attribute of the Money datatype rather than as a separate XML-Element.
The currency attribute should then include a list of valid currencies codes that are supported.
A count of the number of occurrences of something - must therefore be >=0. This is the functional equivalent of the XML nonNegativeInteger datatype.
A measurement of something such as a length or area. All measurements are to 2 decimal places and must be positive.
A string containing a unique identifier for something.
The underlying assumption is that each instance of a class or entity will have a unique identifier assigned to it which can then be assigned to any referencing entity as a reference to the entity instance.
This is a very similar concept to XML ID datatype but is locally defined because of the need to extend the datatype with domain specific attributes.
The Boolean datatype is a redefinition of the XML Schema defined "Boolean". The XSD version is a logical True / False datatype whereas from a data processing perspective it is more likely to be a string based Y/N value. This could be seen as an Enumerated Domain but "Boolean" is so common that it makes more sense to be a base datatype.
