An XSLT processor allows (or should allow) you to pass external 
parameters to a transformation for the global <xsl:param> elements you 
have in your stylesheet. Check the documentation of your XSLT processor.
And if you have an <xsl:param> element in a named template you can call 
that template and pass a parameter in with
    <xsl:call-template name="templateName">
      <xsl:with-param name="paramName" select="xpathHere" />
    </xsl:call-template>
much like in other programming languages you declare a function with 
formal parameters and then call it with actual parameters.

A variable is just meant to store some value.
