Hi Cronos,
Assigning an attribute value in a conversion table is simply adding the attribute name and value to the element in which you are wrapping the format. An example is shown here. Assume these to be the first and second cell in a row of your conversion table:
P:RevisionNote note[type="revision"]
This will wrap the paragraph with format "RevisionNote" into a <note> element with @type set to "revision".
Drop me an email (jang at jang dot nl) and I will send you a PDF of my presentation at the tcworld conference of last year, titled "Advanced Techniques for Conversion to Structured FrameMaker". It might help, if only to show your management that some work does need to be outsourced. :-)
