Competition, for all those XML coders with <i>copious free time</i>:
Write an incredibly small and fast special-purpose XML parser whose
purpose is to locate and read the xml declaration; don't bother reading
any more of the file once this is found.
It should however cope with any well-formed XML instance.
Deduce, from the encoding declaration, what the charset label should be
(the same value, if the encoding declaration is present). If there is no
encoding declaration, apply the rules in the XML 1.0 Recommendation to
determine whether UTF-8 or UTF-16 was used. Thus, there will *always* be
a charset label at this point.
Cache the result in a persistent way; for example, in a file called
Integrate this into the Apache mod_mime (or other suitable place) so
that, for all resources which mod_mime declares to be of type text/xml,
the cached result is automatically used to output a MIME type header
Content-type: text/xml; charset="xxx"
Where xxx is the cached result, provided the cached result exists and is
not older than the datestamp of the xml file; otherwise, refresh the
A special prize bundle of great rarity and desirability will be sent to
the lucky winner.

Once this exists, and is well tested, the next step will be to get it
into the base distribution and installed by default.
