Description

The restriction of simple content complex types is an operation that allows the addition of new constraints to both the attributes and the text node allowed in simple content elements (this reduces the set of valid instances structures). The restriction of the text node is done using the same facets that are available for restricting simple types; the restriction of the attributes is done by providing a list of modified attribute definitions or references. The attribute types used in this list must be identical or explicit derivations by restriction of the types used during the definition of the base type. The controls applied to the attributes must result in a restriction of their definition (for instance, a value may be fixed, an attribute that was optional may become either required or prohibited, etc.).

Restrictions

The same element name (xs:restriction) is used in three different contexts with highly different meanings. Be careful ...
