XSLT and XPath questions could be better posted to the following list:

   http://www.mulberrytech.com/xsl/xsl-list

since the list you've written to tends to focus on the FO vocabulary.

Essentially, then, a copy of the <spotlight_text> element?  I'm confused 
with your reference to "break it up...".

Not sure what you mean here.

Now *that* is going to be difficult for you to guarantee.

></xsl:template>

The value of an element node is the text characters only, none of the 
element nodes.

You haven't yet learned that XSLT and XPath are used to manipulate node 
trees, not to manipulate markup.  The markup on the way in becomes a node 
tree, and the node tree you create becomes markup on the way out, but while 
your stylesheet is functioning you are dealing only with nodes and never 
with tags.  You will not be able to algorithmically measure the markup that 
will be input to or produced from your stylesheet.

If you post your desired output based on the above available input, then 
someone may be able to interpret what exactly you are looking for.

I hope this helps.
