Enumeration Facets

[!INCLUDEssNoVersion] rejects XML schemas with types that have pattern facets or enumerations that violate those facets.

Example

The following schema would be rejected, because the featured enumeration value includes a mixed-case value. It would also be rejected because this value violates the pattern value that limits values to only lowercase letters.

CREATE XML SCHEMA COLLECTION MySampleCollection AS '  
<schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="http://ns" xmlns:ns="http://ns">  
    <simpleType name="MyST">  
       <restriction base="string">  
          <pattern value="[a-z]*"/>  
       </restriction>  
    </simpleType>  
  
    <simpleType name="MyST2">  
       <restriction base="ns:MyST">  
           <enumeration value="mYstring"/>  
       </restriction>  
    </simpleType>  
</schema>'  
GO
