Define key as Follows
<xsl:key match="/root/A"  name="A-with-B" use="property/@id"/>
(Define key as a child of xsl:stylesheet element )


and Use the key like
 <xsl:value-of select="key('A-with-B',property/@id)"/>
  so you send the property Id to the Key and you get      "A"  node which
has the same Property /@id as the one u sent in to the key..
  note that I have assumed ur context node to be B, when I used the key in
the value-of select. make sure you use the right path , depending on your
context node when using the key

 for example, if your template matches B nodes and you use a xsl:for-each
select = "properties" in this template, then you should use  <xsl:value-of
select="key('A-with-B',@id)"/>
Just a  note..
