The lexicographical ordering would make 10.0 > 9.3. In general, A.B > C.D iff A > C or A == C && B > D. When we say the "latest" version we mean "greatest", implying that version numbers increase with time. Does that help?
Sort of. It's what I'd expect from a sensible version comparison. It's just not something I'd ever choose to call lexicographic ordering. IMO, lexicographgic ordering is a basic string comparision so e.g. max "10.0" "9.3" = "9.3" I'd call what you're doing numeric ordering. Does it have a better name, like version-number-ordering, or section-number-ordering (e.g. Section 3.2.5, Section 3.2.6)?
