Response to: Better validation : xs:restriction & xs:pattern
The `<xs:restriction/>` element in a `<xs:simpleType/>` may be used to constrain the value space of data types. `<xs:restriction/>` sub-element `<xs:pattern/>` is used to constrain the value space of data types to literals which match a regular expression.
