Semantics is always contextual. To you, who probably have diving or marine
experience, the statement is true. To me such a sign brings immediate
memories of the fifth Van Halen Album (entitled "Diver Down") which sold
over 4 million copies in the US alone as well as helping me refine my style
of guitar playing while learning the lead parts of "Where have all the good
times gone". (02)

Semantics cannot exist without including the aspect of context. For that
reason alone, I am highly suspecting that everything lower than high level
ontologies needs some form of contextual aspect to modify it. We have
syntax (check), semantic declarations (check), pragmatics (check) but are
still short of some form of reconciliation of instances to the semantic
declarations. (04)
Many attempts at this have failed. Probably the largest of them is the
UN/CEFACT CCTS format which is unique in its' inclusion of context as part
of the core semantics. It hasn't benefited from completion and wide
implementation but I suspect there are a lot of good lessons to learn. (05)
