[Mono-devel-list] XML deserialization - System.FormatException on System.DateTime.ParseExact()

Hmm, sure, then apparently XmlSerializer does not conform to XML
Schema specification and my patch is insane as well as MS.NET.
Note that even if we fix this behavior to conform to W3C spec (it
is desirable), your xs:dateTime instance will still be rejected.

The better solution in that sense is to accept
yyyy-MM-dd(zzzzzzz)? and reject your instance.

So both solutions have pros/cons, I leave it to Lluis who rules ;)
