Hi, Tony, You schema is invalid. You need to read the www.w3.org XML schema documents. Also you might want to get yourself an XML schema validating package (for example, trial ware from XMLSpy.com) and use it to check your schema.

The W3C recommendation implies that restriction is a valid content type (http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/#element-simpleConte nt), so what am I doing wrong? Tony.
