I am getting "Invalid particle derivation by restriction" errors when using
Microsoft VisualStuido.Net to create a typed dataset from the core schema. 
I believe that our AnIML core is not valid and here is the evidence.

"When generating code from a schema you may get the error 'Invalid particle
derivation by restriction'. This may be due to the use of an XSD that does not
conform to the W3C Schema Standard Section 4.4. Derivation by restriction does
not allow you to add or omit elements (unless they are optional in the base
type), it simply allows you to restrict their valid values e.g. set a default
value or set type="string" where previously no type was specified.  Some popular
XML tools do not comply with the XSD standard as they do not mark such schema
as invalid. "

The actual documentation that describes this requirement for derivation
by restriction can be found here.
http://www.w3.org/TR/2001/REC-xmlschema-0-20010502/#DerivByRestrict
where it clearly states (with examples), "Notice that types derived by restriction
must repeat all the components of the base type definition that are to be included
in the derived type: "

The AnIML core fails this requirement in two places:  the complex type TemplateType
derives from ExperimentStepType by restriction.  The complex type VectorValueType
derives from ParameterValueType by restriction.
