Just what it says:  xsd:list is not list.  The value of the derivedBy
attribute is not a QName, just a simple enumeration, whose value must
be 'list' or 'restriction'.

Also note your schema has no targetNamespace, so the reference to
{http://www.XMLBag.com/BasicSchemas.xsd}MyInteger will not work.
