terrestrial biome logical definition does not match text definition

[cmungall]

terrestrial biome http://purl.obolibrary.org/obo/ENVO_00000446
EquivalentTo
biome and determined by some (planetary landmass or part of some planetary landmass)

yet the text definition is A biome which is primarily or completely situated on a landmass.

The OWL definition and the textual definition differ in a crucial way. E.g consider an undersea ecosystem determined by an island. This would be a terrestrial biome by the logical definition but not the textual definition. Text definitions should match logical definitions. If these cannot be aligned then at least the equivalence axiom should be weakened to subclass.

We also have a stray term terrestrial natural environment
http://purl.obolibrary.org/obo/ENVO_01001226

that is not connected to terrestrial biome in either direction.

Terrestrial biome is also missing an is-a parent to terrestrial ecosystem http://purl.obolibrary.org/obo/ENVO_01001790 (see also #1209)
