Brian, >Has anyone implemented "customizations" such as this in respects to the >default schema date/time data type pattern? Bad news, this was discussed on the xmlschema-dev list about a month ago [1] and modifying the lexical space of the built in date type looks grim. There were several suggestions for creating a complexType which handled lexical representation for content but included the actual xsd:date as an attribute (that could be used for ordering/sorting). I think a type was added to the additional type library at http://www.w3.org/2001/03/XMLSchema/TypeLibrary.xsd. If you are not concerned with the actual value space of the type (e.g. what the date text equates to in value) then you could simply create a new simple type which uses an RE pattern. Of course, if you wanted to include all of the logic for dates (such no 30th day in February) then it will be pretty big...
