Ah, I see I completely musunderstood the notation. OK, written English has a 
perfectly adequate notational device for referring to sentences, viz. 
quotation. So here is the grammatical English version, I believe, given your 
explanation so far:    (03)

"Existence" is the name of the following sentence: "An existent is either a 
physical entity, or a physical characteristic, or a physical proposition."    (04)

Which is rather an odd axiom as it is false, since the word "existence" already 
has a different English meaning. But even if we allow that this defines a new, 
technical, usage of the word, this is rather a weak axiom, because it says 
nothing about the world, only about one word meaning. Notice that this does not 
actually use that second quoted sentence, only mentions it. So your axiom only 
names the sentence, it does not claim it to be true. Is that really what the 
mKR is supposed to be saying?    (05)
