[news.eclipse.webtools] XML editor keyref question

[mikrodj@xxxxxxxxxxx (David Gomez)]

Hello everybody, I have a question about keys and keys references in 
eclipse XML editor. 
I have the follow elements defined on my schema 

<xsd:key name="property-name-is-key">
    <xsd:selector xpath="*/class/*/*"/>
    <xsd:field xpath="@name"/>
</xsd:key>

<xsd:keyref name="property-name-referencing-by-method" 
refer="property-name-is-key">    
      <xsd:selector xpath="*/methods/*/class-property"/>
      <xsd:field xpath="@property-name-ref"/>
</xsd:keyref>

<xsd:element name="notified-property">
<xsd:complexType>
<xsd:attribute name="property-name-ref" type="xsd:string" use="required">
</xsd:attribute>
</xsd:complexType>
</xsd:element>

I would like that when I'm editing a element of type notified-property 
under the selector */methods/*/class-property the editor show a combobox 
with attributes "names" under elements "*/class/*/*" according to the 
keyref restriction and helping me out to fill the attribute. 

Is there any way to do it?
Cheers, David.
