Spread to what? AFAICS the way that XMLELEMENT uses AS is a
single-purpose wart (much like a lot of other stuff the SQL committee
invents :-(). I do not see a need to reserve AS in function argument
lists for that purpose. In any case, the proposed meaning here is only
relevant to functions that expose names for their parameters; so in
principle you could still do something like what XMLELEMENT does for any
function that does not create names for its parameters.
