.NET 2.0 gives you an option to allow or disallow xml:* attributes in
the instance documents when the schema doesn't explicitly declare them.

The attributes aren't treated specially by the schema processor: they
are
allowed only if they are declared (explicitly, or using wildcards).

The only attributes that are treated specially are the xsi: attributes,
for
example xsi:type. (And namespace declarations, but those don't count as
attributes.)
