[xsl] concatenated key

["I-Lin Kuo" <ikuoikuo@xxxxxxxxxxx>]

Hi,

Given a node, I'm trying to identify/pull out those nodes in the document 
having the same set of identically named child nodes. For example, given the 
node Alpha in the following, I'd like to pull out the  "Alpha2" node.

<node name="Alpha">
 <node name="a"/>
 <node name="b"/>
</node>
<node name="roman">
 <node name="i"/>
 <node name="ii"/>
</node>
<node name="Alpha2">
 <node name="a"/>
 <node name="b"/>
</node>

The way I'm thinking about doing this is to construct an xsl:key where the 
value of the key consists of a concatenation of all the @name of its 
children and then do a select on the key. However, I can't figure out what 
expression I should have for the use="" attribute of xsl:key, and would 
appreciate any help. Also, if someone has a better approach, I'm open to 
suggestions.
