You do not show how you are working with $factor and that affects the 
answer. You are passing a node in your old code.

If you need a node in the function, then the ways are:

In XSLT 1:

   <xsl:variable name="Fcfactor">
      <xsl:choose>
        <xsl:when test="FCDecimalPlace  != ''">
          <xsl:call-template name="translateDcml">
             <xsl:with-param name="factor" select="FCDecimalPlace"/>
          </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
          <xsl:call-template name="translateDcml">
             <xsl:with-param name="factor" select="LCDecimalPlace"/>
          </xsl:call-template>
        </xsl:otherwise>
      </xsl:choose>
   </xsl:variable>

In XSLT 2:

   <xsl:variable name="Fcfactor">
     <xsl:call-template name="translateDcml">
        <xsl:with-param name="factor" as="node()">
          <xsl:choose>
            <xsl:when test="FCDecimalPlace  != ''">
             <xsl:sequence select="FCDecimalPlace"/>
            </xsl:when>
            <xsl:otherwise>
             <xsl:sequence select="LCDecimalPlace"/>
            </xsl:otherwise>
          </xsl:choose>
       </xsl:with-param>
     </xsl:call-template>
   </xsl:variable>

If you need only the value to be passed then this works with both 
XSLT 1 and XSLT 2 by passing a temporary tree with the value:

   <xsl:variable name="Fcfactor">
     <xsl:call-template name="translateDcml">
        <xsl:with-param name="factor">
          <xsl:choose>
            <xsl:when test="FCDecimalPlace  != ''">
             <xsl:value-of select="FCDecimalPlace"/>
            </xsl:when>
            <xsl:otherwise>
             <xsl:value-of select="LCDecimalPlace"/>
            </xsl:otherwise>
          </xsl:choose>
       </xsl:with-param>
     </xsl:call-template>
   </xsl:variable>

The whole key is to put the choice inside the value of the parameter.

I hope this helps.
