Remarks

This attribute can contain the following values:

Enum	Description
None	Use the derivation restriction defined by the BlockDefault property of the schema, if it exists.
Empty	There are no restrictions on replacements of this element.
Substitution	This element cannot be replaced by a type derived by Substitution.
Extension	This element cannot be replaced by a type derived by Extension.

This property does not prevent derivation, but prevents derivation from replacing the type in an instance. List and union values are not supported for the block property.
