I have tried your schema above and an XML instance I made up with both 
MSXML 4 and with the Xerces Java parser used by the jEdit editor and its 
XML plugin and both handled the schema without problems and depending on 
the content of the sole element flagged a validation error if the 
minInlusive constraint was not fulfilled.
Thus I don't think there is anything wrong with the schema.

What is msv, is that simply a validator? Perhaps the exception happens 
because of some other problems unrelated to the validation features 
Xerces provides.
