Case in XSD register

Question

When I try to register an XSD if the element names are in lower case then when I try to describe the underlying objects i get an error Object doesnt exist even though i can see it in USER_OBJECTS, however if the element names are in upper case then i can describe the objects fine.
Is this a bug or am i doing something wrong. Also i dont seem to be able to specify a name for attributes in the Oracle Object using xdb:SQLName, it just seems to be ignored whenever i register a schema (i have included the xdb namespace)
Any ideas?

Answer 1

A XSD snippet as an example of xdb not functioning how i would expect. I assumed that the element from would be represented by attributes / types called sender rather than fromxxx where x is a number?
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb">
     <xs:element name="content" type="xs:string"/>
     <xs:element name="from" type="xs:string" xdb:SQLName="sender"/>
     <xs:element name="message">
          <xs:complexType>
               <xs:sequence>
                    <xs:element ref="from"/>
                    <xs:element ref="to"/>
