Pull up annotation in restirction

[onacit]

It seems that xs:annotation should be the first element in xs:restriction.

<restriction
  base = QName
  id = ID
  {any attributes with non-schema namespace . . .}>
  Content: (annotation?, (simpleType?, (minExclusive | minInclusive | maxExclusive | maxInclusive | totalDigits | fractionDigits | length | minLength | maxLength | enumeration | whiteSpace | pattern | assertion | explicitTimezone | {any with namespace: ##other})*))
</restriction>
