Not a bad idea, although I'd like to turn the question around and ask about 
plans for the next version of XFML. Not that splinter projects aren't 
useful (that's how we got the good versions of Unix, after all), but it 
would be great to see the next XFML spec incorporate ideas that have been 
helpful -- it would help set direction for faceted classification in general.

The facetmap XML format is already an extension of XFML, in the sense that 
is not supported by basic XFML software but replicates the functionality of 
XFML. It just happens to be a less friendly extension since facetmap and 
XFML were originally independent simultaneous projects.

The idea of a set of XFML extensions that each extend the spec in different 
ways is intriguing, and I wonder what would happen if a developer were to 
want features from a couple different extensions. (Which casts the whole 
set of XFML specs into a facet space! Who are we to extend faceted 
classification specs with such an outdated single-parent hierarchy paradigm? :)
