Getting following Error:

Analyzing your sample code, I suppose you are trying to restrict a complex type to change the type of a local attribute or element.

In this case you should refer a type that is a valid restriction of the original one. In your case you are trying to change the type of the 'Name' attribute from 'StringMin1' to 'ChargeableEntity'. This is an error because the type 'ChargeableEntity' is not a valid restriction of the type 'StringMin1'.

The same problem is related to the type of the 'Data' element. If you want to change it, then you should refer a type that is a valid restriction of the original one.

You can can find more details about complex type derivation rules in one of the XML Schema related books, recommended by us on our website: http://oxygenxml.com/xml_books.html.
