TXSDecimal acts as a wrapper for the simple scalar decimal type that W3C defines for XML schemas. Because this type does not correspond directly to a Delphi or C++ type, it requires special marshaling when used in an invokable interface. TXSDecimal enables this marshaling because it is a descendant of TRemotable. 

To convert a TXSDecimal value to a TBcd value, use the AsBcd property. 

On server applications, instances of TXSDecimal that are input parameters on an invokable interface are automatically created when the method call is unmarshaled and automatically freed after any output parameters or return value are marshaled so that they can be sent to the client. When a TXSDecimal instance is created in a method that was called remotely using an invokable interface, the instance is automatically freed after the value of the TRemotable descendant is marshaled for transport back to the client application. 

The caller of an invokable interface (client) is responsible for creating any TXSDecimal instances that it passes as input parameters, and for freeing any TXSDecimal instances it creates or that are returned as output parameters or method results.
