[xsl] Chunking xml into single-topic docs

["Kessler, Marcy" <marcy.kessler@xxxxxx>]

I'm taking documents that are authored in FrameMaker, converting them
into structured xml files and then using an XSLT to transform them into
DTD compliant single-topic xml documents.

The problem I'm having is that the single-topic files that are created
take the first word of the heading of each section and that is the file
name for the xml file.  However, if the first word is the same in more
than one heading (i.e. Product Overview, and Product Specifications) the
first file is overwritten by the second occurrence and the first file
isn't created.

As a newbie (frantically trying to learn xsl, Xpath, etc. as quickly as
possible), I'm struggling with knowing where to start in fixing the
problem.  I was hoping any of you could point me in the right direction.
Any help would be much appreciated.
Thanks - Marcy

Here is a section of the common.xsl file that I think needs to be
changed:

<xsl:stylesheet version="2.0"
