DITA authoring: conditional profiling attribute values

Hello all, 

We are authoring in structured DITA 1.2 using FrameMaker.

I'm trying to determine if there is an easy way to provide different sets of (selectable) attributes for different product teams. We have 3 product teams, each owning a series of 5-10 products. The values for profiling attributes (platform, product and audience) is unique for each group. Therefore, it doesn't make sense for one group to see the allowable attribute values for another groups's products. I also don't want each writer to type in the value for the product, platform, or audience. I would like these to be selectable from a pre-defined list (such as the Attributes pod).

I know it's possible with other tools (such as Oxygen) to configure a subject scheme map and then add a reference to that subject scheme from the main dita map - doing so allows you to easily select attribute values from a supplied list. I know subject scheme maps are not supported in FrameMaker, but is there any other way to achieve something similar, without having to create different sets of EDDs and templates, which will become cumbersome very quickly.

Thank you in advance.
