It's not a big deal and of course we'd like to avoid showing that page
to anyone, ever. Anyway, would adding a mechanism to the SP to make
error templates more dynamic be a desirable feature?
For example by either calling seperate template files based on
presented languages (iterating over e.g. de_AT, de, with a fallback to
en, stat'ing template.$lang.html in turn) or calling a single template
but provide language selection features within that (though my
attribute checker template code is pretty much write-only as it is).
(I only care about accept-language and the attribute checker template
at this time, as I provide the complete error message text myself,
contrary to, say, sessionError where the error text will come from the
software. I'm not asking for those error messages to be translated).
