Why? UTF-8 is the default, it seems.

2.8 Prolog and Document Type Declaration

In the absence of information provided by an external transport
protocol (e.g. HTTP or MIME), it is a fatal error for an entity
including an encoding declaration to be presented to the XML processor
in an encoding other than that named in the declaration, or for an
entity which begins with neither a Byte Order Mark nor an encoding
declaration to use an encoding other than UTF-8. Note that since ASCII
is a subset of UTF-8, ordinary ASCII entities do not strictly need an
encoding declaration.
