Issue: macrophage EquivalentTo myeloid leukocyte

(Alex, this might be for you please?)

From email thread on GO Editors list: 

>> ADD GO:0014005 'microglia development' GO:0061515 'myeloid cell development'

http://en.wikipedia.org/wiki/Microglia). Still, looking at the inference 
explanation in Protege, could there be a problem here?
> 'macrophage' SubClassOf 'myeloid leukocyte'

link (which make 'microglia' a direct descendant of 'leukocyte') doesn't sound 
quite right to me, but I can't put my finger on it. Ideas?

See explanation (trivial - it's asserted in the genus of the definition)

You could put something on the CL tracker, I'm sure Alex (cc'd) can give a 
detailed answer (or fix if wrong)

For what it's worth, I think the textual definition is problematic:

"A mononuclear phagocyte present in variety of tissues, typically 
differentiated from monocytes, capable of phagocytosing a variety of 
extracellular particulate material, including immune complexes, microorganisms, 
and dead cells." 

Thanks,
Paola
