g-text's are like (well they are) representations, and they may have 
other properties, for example and RDFa document, it contains multiple 
things, one of those things is a serialization/encoding/representation 
of the g-snap.

Thus I have to conclude that we can only have g-snap equivalence and not 
g-text equivalence.

(I think that follows?! always aware how easily I can be wrong, 
especially given the recipients of this mail lol)
