First of all I want to thank everyone that has helped
my understand the basics of xsl! Thanks!  I am trying
to display an image whose path location is in the xml
file.  I am writing fo stylesheet.  Here is a sample
of what my xml looks like.  I read somewhere that I
was to use <fo:inline-graphic> but that is not a valid
tag.  Can someone please help?  TIA.
