Don't use value-of for processing the normal content of elements,
and especially not where there are subelements. Value-of simply
extracts the string value, ignoring all element markup, which is
the opposite of what you want. Instead, use <xsl:apply-templates/>
which means "process the content of this element using any
further templates that apply". Create a template to match "sub"
and put in it whatever is relevant.

But you have a more serious problem, I think: all that extraneous
white-space is going to cause problems if you are producing formatted
output, because you'll have a space after every dollar sign, which
in some circumstances may cause line-breaks to occur in unwanted
locations. Fix the XML so it says:

  <body>Subscriber agrees to pay Company the sum of $<sub 
  name="install"/>, plus tax, if applicable, for the 
  installation (and sale if the System is sold) of the 
  System as follows: $<sub name="down_pmt"/> upon signing 
  this Agreement; $<sub name="pre_wire_pmt"/> upon 
  pre-wiring, if necessary; $<sub name="final_pmt"/>
  upon substantial completion of installation.</body>

or similar.
