Storing data within Docbook?

[Vadim Peretokin <Vadim.Peretokin@nehta.gov.au>]

I'm transforming some data from an XML format into a Docbook table - but not all of the data in the XML is to be displayed in Docbook. I would, however, like to store it in my Docbook XML - because future transformations would like to read my Docbook XML and they'd need all of the data that went into it. I'd rather not introduce a secondary file for storing the extra data - this would bring complications and fragility.

I thought of adding extra columns in the Docbook table and setting them to be hidden - but it doesn't seem to be possible to 'hide' a column easily. Another idea would be to store in in XML comments - which would still be accessible in my transformation as well.

What would be a good pattern to solve my use case?
