According to the link that I mentioned,

infinity       ::=  "Infinity" | "inf"

and "Case is not significant, so, for example, “inf”, “Inf”,
“INFINITY” and “iNfINity” are all acceptable spellings for positive
infinity."

I completely agree with your arguments and the reference manual has
been improved a lot in the recent years.
