Hello Nina,
as far as I know, the many map elements and attributes are not really well supported in FrameMaker, as far as their idiomatic "function" in DITA is concerned. Maps in maps yet are well supported in DITA-FMX, but not in Adobes own structure application pack. I could imagine that this remains so in any "FrameMaker 9" that might come or might not come.
Hope this helps.
With kind regards.
