[xsl] Define a key with cross reference

["Ranjan K. Baisak" <ranjanbaisak@xxxxxxxxx>]

I would appreciate if anybody can help me to key with
cross reference with related elements. The structure
of my XML is :
<root>
<A name="A1">
	<property id="1"/>
	<property id="2"/>
</A>
<A name="A2">
	<property id="1"/>
	<property id="3"/>
</A>
<B name="B1">
	<property id="1"/>
	<property id="2"/>
</B>
<B name="B2">
	<property id="1"/>
	<property id="3"/>
</B>
</root>
I need to define a key which can give me all <A>
elements which are related to <B> related. The
relatioship is through id attribute of property.
E.g. for <B name="B2"><property id="1"/>, I should get
<A name="A1">
	<property id="1"/>
</A>
<A name="A2">
	<property id="1"/>
</A>.

regards,
Ranjan
