vfp.VFPXMLProgId doesn't support cSchemaLocation parameter for XMLUpdateGram(). (Error 2137)

Occurs when Visual FoxPro attempts to use the cSchemaLocation parameter in a custom implementation of XMLUpdateGram with the vfp.VFPXMLProgid. Visual FoxPro does not allow the use of the cSchemaLocation parameter in custom implementations.

• If the cSchemaLocation parameter is required in your custom implementation of XMLUpdateGram, add the value to the schema via your own implementation.
