I don't understand what you are saying. If you want to cast the supplied 
value of the parameter to an appropriate type then using the as attribute
  <xsl:param name="param-name" as="sequenceType"/>
is the way to do that, see <URL:http://www.w3.org/TR/xslt20/#parameters> 
which says

  "The xsl:param  element has an optional as attribute, which specifies 
the required type of the parameter. The value of the as attribute is a 
SequenceType  XP, as defined in [XPath 2.0].

If the as attribute is specified, then the supplied value of the 
parameter is converted to the required type, using the function 
conversion rules."


So using the as attribute does what you want to do, it casts the 
supplied value to the specified type.
