Jim,
If you pull up Crystal's formula editor, you'll find some Type Conversion entries in the list of functions.
However, I'm not sure that should be necessary. I generate XML schemas from typed datasets in VS.NET, and use different data types based on what I need. The resulting schemas look something like the following:
<xs:element name="PaidAmount" type="xs:decimal" minOccurs="0" />
<xs:element name="Name" type="xs:string" minOccurs="0" />
<xs:element name="Approvedflag" type="xs:boolean" minOccurs="0" />
How are the schemas being created? (Through VS.NET, or in another way)
Am I missing something? (I'm not an expert on XML, I've probably learned more about them through .NET than anything else)
