Kobling af flere forskellige XSD'er i et.

Overordnet problemstilling:
Jeg skal have koblet flere forskellige XSD'er sammen i et, hvilket jeg har forsøgt på i nedenstående:


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

<schema
targetNamespace=
"http://rep.oio.dk/ebxml/xml/schemas/cc/2003/02/17/"

<element name="Address">
  <complexType name="AddressSpecificType">
  <sequence>
<element ref="cc:DistrictName" minOccurs="0"/>
<element ref="cc:BuildingIdentifier" minOccurs="0"/>
<element ref="cc:FloorIdentifier" minOccurs="0"/>
<element ref="cc:TownName" minOccurs="0"/>
<element ref="dkcc:PostCodeIdentifier" minOccurs="0"/>
<element ref="brr:HouseNumberCharacter" minOccurs="0"/>
  </sequence>
  </complexType>
</element>
</schema>

Når jeg validerer mit XML-dokument kommer der en fejl i <HouseNumberCharacter></HouseNumberCharacter> i nedenstående XML-dokument. Det er vist fordi den ikke tilgår stierne i det ovenstående schema.

Er der nogle der kan hit ud af det?
