XSD keyRef

[Kent Boogaart]

Hello,

I have a complex type defined in its own schema as follows:

<xsd:complexTyp e name="myType">
<xsd:complexCon tent>
<xsd:extensio n base="myBaseTyp e">
<xsd:attribut e name="parentId" type="xsd:strin g" use="optional"/>
</xsd:extension>
</xsd:complexCont ent>
</xsd:complexType >

I want to apply a keyRef so that the parentId attribute must refer to a
valid ID (defined elsewhere in another schema). However, as far as I can
tell, XSD only allows you to specify a keyRef inside an element declaration.
But I don't want to declare an element. Does anyone know how I can declare a
keyRef without requiring the element?

Thanks,
Kent

You can't. key/kerefs must be declared on an element. It could be either a
global element or a local element.

Thanks for the reply. Is this a known flaw in XSD? Will something be done
about it? It seems a bit limiting to me. I have a similar problem trying to
declare uniqueness on a complex type's outer element's children.

Thanks again,
Kent
