Re: [xsl] recursion with Muenchean Grouping...

If you are grouping using keys, you just have to use a key that has the
same value for every item that you want grouped, and has a different
value for any pair of items that should not be grouped.

In your case you appear to want to group things together if 
a) they have the same parent and
b) they have the same name

so use
a key of concat(generate-id(..),'!',@name)
in both the use attribute of the xsl:key, and in the key() function.

So your key will be a string made up of a unique identifier for a
parent, and the name of the element, separated by "!".
I think Jeni has more examples of using concat to build up compound keys
at her site.
