It is not alright:

the complexType "ID" should have instead been a simpleType.

http://www.w3.org/TR/xmlschema-1/#src-ct point 2 is fulfilled but
point 2 of http://www.w3.org/TR/xmlschema-1/#ct-props-correct is not:

2 If the {base type definition} is a simple type definition, the {derivation
method} must be extension.
