=head1 NAME

DateTime::Format::XSD - Format DateTime according to xsd:dateTime

=head1 VERSION

version 0.5

=head1 SYNOPSIS

  my $str = DateTime::Format::XSD->format_datetime($dt);

=head1 DESCRIPTION

XML Schema defines a usage profile which is a subset of the ISO8601
profile. This profile defines that the following is the only possible
representation for a dateTime, despite all other options ISO provides.

   YYYY-MM-DD"T"HH:MI:SS(Z|[+-]zh:zm)

This module is a subclass of DateTime::Format::ISO8601, therefore it
will be able to parse all other ISO options, but will only format it
in this exact spec.
