[tdwg-content] Darwin Core Proposal - environment terms (biome)

I haven't looked at the definition given to "biome" in ENVO, but based 
on what I believe is the common consensus on what a biome is (a major, 
large-scale set of plant and animal communities occupying a geographic 
region), it doesn't seem right to apply that term to "leaf litter".  
There are a number of standard lists of the world's biomes and they 
include large-scale regions like "temperate deciduous forest", not 
small-scale features.
