Customizing the FIXML schema

Hello,

I am using FIXML 5.0 SP2, and I would like to add some custom fields to one of the message types (TradeCaptureReport_message_t).

On the FIX WIKI (http://fixwiki.org/fixwiki/FPL:FIXML_Syntax#Defining_a_custom_field) I read that this should be possible, but my attempts so far have been unsuccessful.

I have attempted redefining the xs:group TradeCaptureReportElements in the tradecapture-impl xsd (so that I could add my custom element to the group), but when parsing the schema with XMLSpy I get the error that the component TradeCaptureReportElements is already defined in tradecapture-base.

What would be the proper way of customizing the schema? Most helpful would be some example code from an impl xsd.

Best regards,
Erik
