Yes, it's all described in the DFDL spec. Set external='yes' on dfdl:defineVariable.

Not yet supported by IBM DFDL though for user-defined variables, only for the 4 pre-defined variables.

Subject:        [DFDL-WG] passing parameters to DFDL?
Sent by:        dfdl-wg-bounces@ogf.org

XSLT has an ability to pass an external value to a parameter within the stylesheet, using <xsl:param>.
 
Does DFDL have a similar capability?  Does dfdl:defineVariable allow this?
