You're correct that RFC-19 is not clear on which parameters will be
mapped. I think this should be corrected in the RFC and it should
explicitly list all parameters that are mappable and how they operate.
I had the same question and asked not long ago on this list about
mapping of colors and Steve confirmed that this would be supported as
well. However I had assumed that COLOR would map to a single field and
not to 3 fields. Since there are multiple possible ways to do the
mapping that's one more reason to update the RFC to better specify how
colors will be mapped.
