Hi, 

 

Here's a newbie question. I have an xml like this:

 

<?xml version="1.0" encoding="UTF-8"?>

It is validated against this schema:

                           <xs:element name="JJJ">

                                 <xs:complexType>

                                        <xs:sequence>

                                               <xs:element name="LLL"
type="xs:string"/>

                                        </xs:sequence>

                                        <xs:attribute name="JJJID"
type="xs:string" use="required"/>

                                 </xs:complexType>

                           </xs:element>

                    </xs:sequence>

             </xs:complexType>

       </xs:element>

</xs:schema>

 

 

What I want is to validate that all HHHs/HHH/JJJIDs exist in (the attribute)
the list of JJJs/JJJ/JJJID and it works. 

 

My question, is there a way to declare a key/keyref for JJJIDKey that works
for all CCC's. Above I've created a "aJJJIDKey", "bJJJIDKey" and I would
like to get around this.

 

Thanks

Marcus
