Nested XML search support in Sphinx?

Does Sphinx xmlpipe2 supports nested XML strcuture for search? For example, something like this.

<sphinx:document id="1234">
<attr1>some data</attr1>
<attr2>some more</attr2>
<tags>
    <tag id="23">One</tag>
    <tag id="24">Two</tag>
</tags>
<misc>some more info</misc>
</sphinx:document>

If not, what's the best possible approach for storing associated data in a search efficient manner.
