Selecting node sets for page by page output - without usingf

Hello all,

I am stumped on this one. I have an XML Doc like this:

<?xml version="1.0" ?>

As you can see, each topicStoryContainer has a topic and a storyList, and
all the topicStoryContainers make up a topicStoryContainerList. I want to
write an XSLT that grabs five nodes per page, based on startRange and
endRange parameters, and creates appropriate navigation for previous and
next pages. 

**So my question is this**: how do I grab five <story>s per page, in
sequence, with topic headings inserted in the appropriate places, _without_
using <xsl:for-each> or <xsl:if>?

I've tried using the position() function to determine ranges of things, but
since this is contextual, the topic elements seem to reset it for each
storyList.

Is this even possible? I am curious since I have been told it's much more
efficient and desirable to use <xsl:apply-templates> and "modes" rather than
using a lot of explicit logical branching for this sort of thing.

Thanks,
aaron
