I think that by analogy to arity, where concat#2 and concat#3 are
strictly speaking not the same function, we would have distinct
local:doesThing#3@userDefinedMode1 and
local:doesThing#3@userDefinedMode2 as distinct functions.

Do we want to emulate a template entirely in a function or have a
function that allows XPath to either call or apply templates? I'd think
it's the later; if it's the former, that's trying to stuff template
functionality into functions as a mechanism and I don't think it will
go.  (As a distinct concern, it would also amount to deciding that XSLT
and XQuery ought to be one language and I think there are sound reasons
not to do that.)
