Description:
When validating the XML Schema for Schemas (or equivilent) the validation fails 
with error found:Unknown base type 'xs:anySimpleType' for a type 'string' on 
line: 64
As the Schema Schema is normative this must be a bug.
I see lots of other errors from this schema but they are probably fallout from 
not finding the base type for all of the built in types!

Steps to Reproduce: 
cut the two parts of the XML Schema Schema out of the 
http://www.w3.org/TR/xmlschema-1 and http://www.w3.org/TR/xmlschema-2.
saved in files normModXMLSchema.xsd and normModDataType.xsd

file changes:

1) removed doctype DTD stuff from top of files (yuk!)
2) changed import statements to use new datatype file name.
3) changed target name space to "http://www.w3.org/2001/XMLSchema/mod" in both 
files.
4) defined new name space xmlns:modxs="http://www.w3.org/2001/XMLSchema/mod" in 
both files.
5) did a replace on all instances of "xs: to "modxs:
6) changed all instances of "modxs:anySimpleType" to "xs:anySimpleType"
7) changed name="schema" to name="mySchema" (so that my tools stopped 
complaining about schema not being in the right namespace)
8) modified a schema I had previously created to use <mySchema> and set the 
schema location to normModXMLSchema.xsd.
9) validate the modified schema instance against the modified schema schema.

Actual Results:  

the first few lines of bug output are:
main (15:02:55): error found:Unknown base type 'xs:anySimpleType' for a 
type 'string' on line: 64
main (15:02:55): error found:cos-applicable-facets: Facet 'whiteSpace' is not

The schema schema spec clearly states that anySimpleType exists:

4.1.6 Simple Type Definition for anySimpleType
There is a simple type definition nearly equivalent to the simple version of 
the ur-type definition present in every schema by definition. It has the 
following properties

Have also seen this bug with Xerces version 1.4.4 and 2.0.0

I can send you the test files if you want them.
