I'm not sure.
Let me be more clear on my intentions:

The lexicon XSD has (among other things) the following definition:

    <xsd:element name="lexicon" type="LexiconType">
        <xsd:key name="itemIdKey">
            <xsd:selector xpath="item"/>
            <xsd:field xpath="id"/>
        </xsd:key>
    </xsd:element>


I will have one XML instance of the lexicon XDS, say lexicon.xml.
I will also have some other XSD say document.xsd and an instance of it, say
document.xml.

I want to be able to define an element or attribute in document.xml which can 
point to the item id in lexicon.xml.

My questions are:
	1. How to define such a pointer in document.xsd
	2. How to actually point using such a pointer from some element
		or attribute in document.xml to lexicon.xml?

Thanks.
