1. Do not understand your structure, but:
<items>
<item attribute="value">
</item>
<item attribute="anothervalue">
</item>
</items>
could match multiple rows.
2. I wonder if the item tag attribute that matches the structure of the
contained data is perhaps leading you to create dynamic structures?
Interesting. Is that parsed by XSL switch statements that use the
variant structure? Something tells me you may need a uniformly named
container for the object being defined therein?
I am fairly new to XSL so forgive me if I am barking up wrong trees
