For example, I want to define a named template ("TABLE_CELL") that wraps a <TD></TD> set around whatever calls it.  I want to use this for all my XML elements so that I can change the BGCOLOR attribute in it and have the change apply throughout.

Well you need to pass a parameter indicating whether you need BOLD or
not because you can only append to the result tree. So you need to get
all the things (BGCOLOR and BOLD etc.) at one go and then write to the
output  

  <xsl:template name="TABLE_CELL">
   <xsl:param name="BOLD" />
   <xsl:when test='BOLD = "Y"'>
     <TD BGCOLOR="#000000">
        <B>
          <xsl:value-of select="."/>
        </B>
     </TD>
   </xsl:when>
   <xsl:otherwise>
     <TD BGCOLOR="#000000">
        <xsl:value-of select="."/>
     </TD>
    </xsl:otherwise>
  </xsl:choose>
 </xsl:template>

 Now if you want with BOLD you would say

   <xsl:call-template name="TABLE_CELL">
      <xsl:with-param name="BOLD" select='"Y"' />
   </xsl:call-template>   

 and if you do not want BOLD then

   <xsl:call-template name="TABLE_CELL">
      <xsl:with-param name="BOLD" select='"N"' />
   </xsl:call-template>
