Preserving Idref in Cross Reference when Converting from Unstructured to Structured

Hi,

I am currently in the process of converting from Unstructured FrameMaker files to DITA using FrameMaker 11.

When I structure the document using the conversion table, I'd like to be able to save the Idref value for the cross-reference as an attribute in the element it is wrapped in. At the moment, when I structure the document, all I can manage is to wrap the text in a <xref> element.

Is this possible?

Cheers,

Zane
